 That should be R_MIPS_REL16 AFAICT, reloc #33 according to MIPS NewABI 
documentation[1]:

    Name      Value  Field   Symbol  Calculation
R_MIPS_REL16   33    V-hw16   any        S+A

and we have all the bits including a howto in place.  I wonder what 
happened that we never had it linked with BFD_RELOC_16.
