Have you tried mainline binutils?  A patch I committed 2014-03-08 ought to have
fixed this issue.

BTW, it's not so simple as just changing from complain_overflow_bitfield to
complain_overflow_signed.  If you're using ADDR16 relocs on for example, ori,
then you want unsigned overflow checking!  Which is why the old code used
complain_overflow_bitfield..

Search elf32-ppc.c for the following comment
      /* 16-bit fields in insns mostly have signed values, but a
     few insns have 16-bit unsigned values.  Really, we should
     have different reloc types.  */
