--- Comment #2 from Paul E. Murphy <murphyp at linux dot vnet.ibm.com> ---
pwr and pwr2 machine options select bfd_arch_rs6000 machine. The elf backend
bits for ppc seem to assume a bfd_arch_powerpc machine.

The mismatch is visible when _bfd_elf_set_arch_mach is called, fails, and the
failure is quietly ignored when setting up the output object file.

I suspect there is more history between the powerpc and rs6000 backends that I
don't understand yet. Should the assembler generate an error instead of trying
to generate an elf object for very, very old power cpus?
