 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.
