	PR libstdc++/31717 
	* acinclude.m4 (GLIBCXX_ENABLE_CLOCALE): Re-organize. Sanity check
	gnu locale model requests to make sure it will work for the requested
	target. Add checks for strxfrm_l, strerror_l when in gnu locale,
	and strerror_r everywhere.
	* aclocal.m4: Regenerated.
	* configure: Regenerated.
	* config.h.in: Regenerated.
