--- Comment #3 from Alan Modra <amodra at gmail dot com> ---
Yes, the problem is that the powerpc ELF backends only support bfd_arch_powerpc
(ELF_ARCH in elf32-ppc.c and elf64-ppc.c) and we don't override
bfd_set_arch_mach to do anything special, so the default _bfd_elf_set_arch_mach
rejects bfd_arch_rs6000.

On the other hand, the xcoff backends support both bfd_arch_rs6000 and
bfd_arch_powerpc.

I think the correct thing to do is simply change ppc_arch to always return
bfd_arch_powerpc when OBJ_ELF.  I'm testing a patch to do that.
