* write.c (fixup_segment): Handle ABS-sym in -sym case rather than
sym-sym case.
* config/obj-coff.c (fixup_segment): Likewise. Permit negative
symbols if TC_M68K.
* config/tc-m68k.c (tc_coff_fix2rtype): If fx_tcbit is set, return
R_RELLONG_NEG.
(tc_gen_reloc): If fx_tcbit is set, abort.
(md_apply_fix_2): For a negative reloc, move fx_subsy to fx_addsy,
and set fx_tcbit.
Permits generating negative relocs for m68k COFF.
