Add SPARC ELF PIC support.

	* write.c (fixup_segment): Pass fixP to TC_RELOC_RTSYM_LOC_FIXUP,
	not fixP->fx_r_type.
	* config/tc-sparc.c (sparc_pic_code): New global variable.
	(md_apply_fix): If generating PIC, adjust fx_addnumber for any non
	PC relative reloc.
	(tc_gen_reloc): If generating PIC, adjust various reloc types.
	Remove fx_pcrel assert, since it is no longer true.
	(md_parse_option): Handle -K PIC.
	* config/tc-sparc.h (sparc_pic_code): Declare if OBJ_ELF.
	(TC_RELOC_RTSYM_LOC_FIXUP): Define if OBJ_ELF.
	(tc_fix_adjustable): Don't adjust PC relative relocs if PIC.
	* config/tc-i386.h (TC_RELOC_RTSYM_LOC_FIXUP): Take a fixp, not a
	reloc type.
