GCC configure should say that the linker does *not* support .hidden.
For static-only linking (the only mode supported on this simulator-only
system) this shouldn't really matter. But, different code is actually
used (not just the attribute-hidden decorations), so different bugs are
exposed. Like PR54373. There's a difference for in-tree and separate
build/out-of-tree binutils and this makes the out-of-tree-binutils case
align to the in-tree one, where the linker is found to emit something
that doesn't match the ELF test; the `grep 'EMUL = .*elf' ../ld/Makefile`
fails. I'll hold this until the non-configury bugs in PR54373 are fixed.
gcc:
* configure.ac (out-of-tree linker .hidden support) Set to "no"
for mmix-knuth-mmixware.
* configure: Regenerate.
