Even if GCC64 is able to boostrap without libffi being a
FAT library on AIX, the tests for "-maix32" are not working
without it.
libffi/ChangeLog:
2021-10-21 Clément Chigot
* Makefile.am (tmake_file): Build and install AIX-style FAT
libraries.
* Makefile.in: Regenerate.
* include/Makefile.in: Regenerate.
* man/Makefile.in: Regenerate.
* testsuite/Makefile.in: Regenerate.
* configure (tmake_file): Substitute.
* configure.ac: Regenerate.
* configure.host (powerpc-*-aix*): Define tmake_file.
* src/powerpc/t-aix: New file.
I've already made a PR to libffi itself in order to add the common part of
this patch to it. But for now, it's still unmerged:
https://github.com/libffi/libffi/pull/661.
