I don't see what the relocation handling in elf_link_input_bfd()
has to do with archives. I want to catch the case when somebody tries
to link together MIPS o32, n32 ad n64 files.

IIRC some time ago there was a patch to detect this for MIPS only,
but I found my patch to be useful for my MIPS NewABI development.
At least it will not harm and work as fallback if something goes wrong.

Ok to apply it?
