	(MACHINE_STATE_SAVE, MACHINE_STATE_RESTORE): Use %g4 instead of %g2
	as sparc64 block profiling register.
	* config/sparc/sparc.c (sparc_override_options): Allow block

	profiling register.
	* config/sparc/linux64.h (MACHINE_STATE_*): Only provide these
	macros on TARGET_ARCH32. sparc.h has macros good enough for sparc64.
	* config/sparc/sol2.h (MACHINE_STATE_*): Likewise.
