* builtin-attrs.def (STRERRNOC): New macro.
	(STRERRNOP): New macro.
	(ATTR_ERRNOCONST_NOTHROW_LEAF_LIST): New attr list.
	(ATTR_ERRNOPURE_NOTHROW_LEAF_LIST): New attr list.
	* builtins.def (ATTR_MATHFN_ERRNO): Use
	ATTR_ERRNOCONST_NOTHROW_LEAF_LIST.
	(ATTR_MATHFN_FPROUNDING_ERRNO): Use ATTR_ERRNOCONST_NOTHROW_LEAF_LIST
	or ATTR_ERRNOPURE_NOTHROW_LEAF_LIST.
