liblzma: Fix x86-64 movzw compatibility in range_decoder.h
Support for instruction "movzw" without suffix in "GNU as" was
added in commit [1] and stabilized in binutils 2.27, released
in August 2016. Earlier systems don't accept this instruction
without a suffix, making range_decoder.h's inline assembly
unable to build on old systems such as Ubuntu 16.04, creating
error messages like:

    lzma_decoder.c: Assembler messages:
    lzma_decoder.c:371: Error: no such instruction: `movzw 2(%r11),%esi'
    lzma_decoder.c:373: Error: no such instruction: `movzw 4(%r11),%edi'
    lzma_decoder.c:388: Error: no such instruction: `movzw 6(%r11),%edx'
    lzma_decoder.c:398: Error: no such instruction: `movzw (%r11,%r14,4),%esi'

Change "movzw" to "movzwl" for compatibility.

CMake: Link xz against Threads::Threads if using pthreads
The liblzma target was recently changed to link against Threads::Threads
with the PRIVATE keyword. I had forgotten that xz itself depends on
pthreads too due to pthread_sigmask(). Thus, the build broke when
building shared liblzma and pthread_sigmask() wasn't in libc.

Thanks to Peter Seiderer for the bug report.

Build: Prepend, not append, PTHREAD_CFLAGS to LIBS
It shouldn't make any difference because LIBS should be empty
at that point in configure. But prepending is the correct way
because in general the libraries being added might require other
libraries that come later on the command line.

Build: Use AC_LINK_IFELSE to handle implicit function declarations
It's more robust in case the compiler allows pre-C99 implicit function
declarations. If an x86 intrinsic is missing and gets treated as
implicit function, the linking step will very probably fail. This
isn't the only way to workaround implicit function declarations but
it might be the simplest and cleanest.

The problem hasn't been observed in the wild.

There are a couple more AC_COMPILE_IFELSE uses in configure.ac.
Of these, Landlock check calls prctl() and in theory could have
the same problem. In practice it doesn't as the check program
looks for several other things too. However, it was changed to
AC_LINK_IFELSE still to look more correct.

Similarly, m4/tuklib_cpucores.m4 and m4/tuklib_physmem.m4 were
updated although they haven't given any trouble either. They
have worked all these years because those check programs rely
on specific headers and types: if headers or types are missing,
compilation will fail. Using the linker makes these checks more
similar to the ones in cmake/tuklib_*.cmake which always link.

Build: Use AC_LINK_IFELSE instead of -Werror
AC_COMPILE_IFELSE needed -Werror because Clang <= 14 would merely
warn about the unsupported attribute and implicit function declaration.
Changing to AC_LINK_IFELSE handles the implicit declaration because
the symbol __crc32d is unlikely to exist in libc.

Note that the other part of the check is that #include <arm_acle.h>
must work. If the header is missing, most compilers give an error
and the linking step won't be attempted.

Avoiding -Werror makes the check more robust in case CFLAGS contains
warning flags that break -Werror anyway (but this isn't the only check
in configure.ac that has this problem). Using AC_LINK_IFELSE also makes
the check more similar to how it is done in CMakeLists.txt.

Build: Sync the compile check changes from CMakeLists.txt
It's nice to keep these in sync. The use of main() will later allow
AC_LINK_IFELSE usage too which may avoid the more fragile -Werror.

CMake: Always add pthread flags into CMAKE_REQUIRED_LIBRARIES
It was weird to add CMAKE_THREAD_LIBS_INIT in CMAKE_REQUIRED_LIBRARIES
only if CLOCK_MONOTONIC is available. Alternative would be to remove
the thread libs from CMAKE_REQUIRED_LIBRARIES after the check for
pthread_condattr_setclock() but keeping the libs should be fine too.
Then it's ready in case more pthread functions were wanted some day.

CMake: Fix three checks if building with -flto
In CMake, check_c_source_compiles() always links too. With
link-time optimization, unused functions may get omitted if
main() doesn't depend on them. Consider the following which
tries to check if somefunction() is available when <someheader.h>
has been included:

    #include <someheader.h>
    int foo(void) { return somefunction(); }
    int main(void) { return 0; }

LTO may omit foo() completely because the program as a whole doesn't
need it and then the program will link even if the symbol somefunction
isn't available in libc or other library being linked in, and then
the test may pass when it shouldn't.

What happens if <someheader.h> doesn't declare somefunction()?
Shouldn't the test fail in the compilation phase already? It should
but many compilers don't follow the C99 and later standards that
prohibit implicit function declarations. Instead such compilers
assume that somefunction() exists, compilation succeeds (with a
warning), and then linker with LTO omits the call to somefunction().

Change the tests so that they are part of main(). If compiler accepts
implicitly declared functions, LTO cannot omit them because it has to
assume that they might have side effects and thus linking will fail.
On the other hand, if the functions/intrinsics being used are supported,
they might get optimized away but in that case it's fine because they
really are supported.

It is fine to use __attribute__((target(...))) for main(). At least
it works with GCC 4.9 to 14.1 on x86-64.

CI: Workaround buggy config.guess on Ubuntu 22.04LTS and 24.04LTS
Check for the wrong triplet from config.guess and override it with
the --build option on the configure command line. Then i386 assembly
autodetection will work.

These Ubuntu versions (and as of writing, also Debian unstable)
ship config.guess version 2022-01-09 which contains a bug that
was fixed in version 2022-05-08. It results in a wrong configure
triplet when using CC="gcc -m32" to build i386 binaries.

CMake: Link Threads::Threads as PRIVATE to liblzma
This way pthread options aren't passed to the linker when linking
against shared liblzma but they are still passed when linking against
static liblzma. (Also, one never needs the include path of the
threading library to use liblzma since liblzma's API headers
don't #include <pthread.h>. But <pthread.h> tends to be in the
default include path so here this change makes no difference.)

One cannot mix target_link_libraries() calls that use the scope
(PRIVATE, PUBLIC, or INTERFACE) keyword and calls that don't use it.
The calls without the keyword are like PUBLIC except perhaps when
they aren't, or something like that... It seems best to always
specify a scope keyword as the meanings of those three keywords
at least are clear.

tuklib_integer: Fix building on OpenBSD/sparc64 that uses GCC 4.2
GCC 4.2 doesn't have __builtin_bswap16() and friends so tuklib_integer.h
tries to use OS-specific byte swap methods instead. On OpenBSD those
macros are swap16/32/64 instead of bswap16/32/64 like on other *BSDs
and Darwin.

An alternative to "#ifdef __OpenBSD__" could be "#ifdef swap16" as it
is a macro. But since OpenBSD seems to be a special case under this
special case of "*BSDs and Darwin", checking for __OpenBSD__ seems
the more conservative choice now.

Thanks to Christian Weisgerber and Brad Smith who both submitted
the same patch a few hours apart.

CMake: Fix liblzma filename in Windows environments
This is a mess because liblzma DLL outside Cygwin and MSYS2
is liblzma.dll instead of lzma.dll to avoid a conflict with
lzma.dll from LZMA SDK.

On Cygwin the name was "liblzma-5.dll" while "cyglzma-5.dll"
would have been correct (and match what Libtool produces).
MSYS2 likely was broken too as it uses the "msys-" prefix.

This change has no effect with MinGW-w64 because with that
the "lib" prefix was correct already.

With MSVC builds this is a small breaking change that requires developers
to adjust the library name when linking against liblzma. The liblzma.dll
name is kept as is but the import library and static library are now
lzma.lib instead of liblzma.lib. This is helpful when using pkgconf
because "pkgconf --msvc-syntax --libs liblzma" outputs "lzma.lib"
(it's converted from "-llzma" in liblzma.pc). It would be easy to
keep the liblzma.lib naming but the pkgconf compatibility seems worth
it in the long run. The lzma.lib name is compatible with MinGW-w64
too as -llzma will find also lzma.lib.

vcpkg had been patching CMakeLists.txt this way since 2022 but I
learned this only recently. The reasoning for the patch makes sense,
and while this is a small breaking change with MSVC, it seems like
a decent compromise as it keeps the DLL name the same.

2022 patch in vcpkg: 0707a17ecf/ports/liblzma/win_output_name.patch
See the discussion: https://github.com/microsoft/vcpkg/pull/39024

Thanks to Vincent Torri for confirming the naming issue on Cygwin.

Fix version.sh compatiblity with Solaris
The ancient /bin/tr on Solaris doesn't support '\n'.
With /usr/xpg4/bin/tr it works but it might not be in PATH.

Another problem was that sed was given input that didn't have a newline
at the end. Text files must end with a newline to be portable.

Fix both problems:

  - Handle multiline input within sed itself to avoid one tr invocation.
    The default sed even on Solaris does understand \n.

  - Use octals in tr -d. \012 works for ASCII "line feed", it's even
    used as an example in the Solaris man page. But we must strip
    also ASCII "carriage return" \015 and EBCDIC "next line" \025.
    The EBCDIC case got handled with \n previously. Stripping \012
    and \015 on EBCDIC system won't matter as those control chars
    won't be present in the string in the first place.

An awk-based solution could be an alternative but it might need
special casing on Solaris to used nawk instead of awk. The changes
in this commit are smaller and should have a smaller risk for
regressions. It's also possible that version.sh will be dropped
entirely at some point.
