	#undef RESOLVE.

	* time/tzset.c: Include <libc-lock.h>.
	(__tzset_lock): New lock variable.
	(tzset): New function (weak defn), no longer weak alias for __tzset.
	Call __tzset while holding __tzset_lock.
	* time/localtime.c: Include <libc-lock.h>.
	(__localtime_r): Hold __tzset_lock while doing the work.
