* sparc-tdep.c (SPARC_HAS_FPU): Define. 

(sparc_extract_return_value): New function, required to handle
	machines without floating point.
	(sparc_store_return_value): Ditto.
	* config/sparc/tm-sparc.h (EXTRACT_RETURN_VALUE): Call
	sparc_extract_return_value instead of using inline code.
	(sparc_extract_return_value): Declare.
	(STORE_RETURN_VALUE): Call sparc_store_return_value instead
	of using inline code.
	(sparc_store_return_value): Declare.
