So I have followed your advice after all and made a minimal change (see
commit 4df995c77118 ("MIPS/opcodes: Only call `bfd_mips_elf_get_abiflags'
if BFD64")), because in such a configuration we may still have other MIPS
BFD targets configured, such as ECOFF, so the disassembler has to remain
fully functional for `objdump' at least.
