Re-confirmed:

static const bfd_arch_info_type *
mips_compatible (const bfd_arch_info_type *a, const bfd_arch_info_type *b)
{
  if (a->arch != b->arch)
    return NULL;

  /* Machine compatibility is checked in
     _bfd_mips_elf_merge_private_bfd_data.  */

  return a;
}

I will update my patch accordingly... This probably warrants a function,
probably in gdbarch-utils.
