liblzma: Check HAVE_USABLE_CLMUL before omitting CRC64 table.
If liblzma is configured with --disable-clmul-crc CFLAGS="-msse4.1 -mpclmul", then it will fail to compile because the generic version must be used but the CRC tables were not included.

// so that in 32-bit builds crc64_x86.S won't break due to a missing table.
