[patch, libfortran, committed] Restore bootstrap on non-x86* systems

Hello world,

I have committed the attached patch as obvious as r248519 after testing
that it does indeed work on powerpc64-unknown-linux-gnu and that
it passes regression-test on that machine.

Sorry for the breakage. I'll use the gcc compile farm machines
in the future to test any such changes.

Regards

	Thomas

	PR boostrap/80889
	* acinclude.m4: Also set HAVE_AVX128 on the false
	branch of LIBGFOR_CHECK_AVX128.
	* configure:  Regenerated.
