glibc: Don't build with -Werror for powerpc64+glibc-2.32
When building powerpc64+glibc-2.32 we see the following error:
[ALL ] In file included from ../sysdeps/powerpc/powerpc32/power4/multiarch/wordcopy-ppc32.c:26,

This seems to only trigger for powerpc64. Other architectures build
cleanly. For now avoid specifying -Werror for powerpc64+glibc-2.32.
