	* elf64-sparc.c (sparc64_elf_howto_table): Fix dst_mask for
	R_SPARC_DISP32.  Support R_SPARC_PLT32 and R_SPARC_PLT64.
	(sparc_reloc_map): Add BFD_RELOC_16_PCREL, BFD_RELOC_64_PCREL
	and BFD_RELOC_SPARC_PLT32.
	(sparc64_elf_check_relocs): Handle R_SPARC_PLT32 and R_SPARC_PLT64.

	* 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.
