Possible problem with gas on MIPS

Yes, you're actually right.  It has been missed out.  We do shift the offsets
right by 2 when we link objects including R_MIPS_PC16 with gld.  This is 
however nothing we want to generate with gas.  IRIX as is actually reluctant
to assemble branches to symbols as well.  I think IRIX ld pukes on R_MIPS_PC16
whenever it gets the chance.
