Actually, I meant R_MIPS_PC16 aka BFD_RELOC_16_PCREL, which will
coincidentially have similiar properties than R_MIPS_GNU_REL16_S2
aka BFD_RELOC_16_PCREL_S2, and which I expect to handle most
things in gas in a similiar way.

No, I just want to avoid overcareful code removal in this area
when ELF external branches support would still need half of it.

Stay with the removal. :-)
