sparc.h (ASM_PREFERRED_EH_DATA_FORMAT, [...]): Define. 

* config/sparc/sparc.h (ASM_PREFERRED_EH_DATA_FORMAT,
	ASM_OUTPUT_DWARF_PCREL): Define.
	* config/sparc/sol2.h (ASM_PREFERRED_EH_DATA_FORMAT): Define.
	* configure.in (HAVE_AS_SPARC_UA_PCREL): Check whether as supports
	.uaword %r_disp32() and linker handles it correctly.
	* configure, config.in: Rebuilt.
