How is this supposed to work?  R_MIPS_PC16 doesn't shift out the lower two
bits of the offset, so the branch instructions can not possibly use this
relocation type.  However can do this with the R_MIPS_GNU_REL16_S2 relocation
which is a Cygnus extension.

I tried it and it goes through the assembler if you use -membedded-pic.  I
have not tested it any further though.
