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.

Upstream fix:
https://git.savannah.gnu.org/cgit/config.git/commit/?id=f56a7140386d08a531bcfd444d632b28c61a6329
