* write.c (adjust_reloc_syms) [RELOC_REQUIRES_SYMBOL]: If no symbol is present

(i.e., relocation against absolute), create a phony local symbol, and use it in
the reloc.
(fixup_segment): When adjusting a reloc with an absolute symbol, have
TC_FORCE_RELOCATION control clearing add_symbolP too.

* config/tc-sparc.h (RELOC_REQUIRES_SYMBOL): Define.
