sparc.c (sparc_profile_hook): If NO_PROFILE_COUNTERS, don't generate and pass a label into mcount.

	* config/sparc/sparc.c (sparc_profile_hook): If
	NO_PROFILE_COUNTERS, don't generate and pass a label
	into mcount.
	* config/sparc/linux.h (NO_PROFILE_COUNTERS): Define as 1.
	* config/sparc/linux64.h (NO_PROFILE_COUNTERS): Likewise.
