* config/tc-sparc.h (TC_PARSE_CONS_EXPRESSION): Define.
(sparc_cons): Provide prototype.
* config/tc-sparc.c (tc_gen_reloc): Handle BFD_RELOC_*_PCREL and
BFD_RELOC_SPARC_PLT{32,64}. Enumerate for which relocs
reloc->addend = fixp->fx_addnumber shouldn't be done instead of
enumarating for which pc relative ones it should be done.
(sparc_cons_special_reloc): New variable.
(sparc_cons): New function.
(cons_fix_new_sparc): Use sparc_cons_special_reloc.
* testsuite/gas/sparc/pcrel.s: New test.
* testsuite/gas/sparc/pcrel.d: Expected output.
