linkage.m4 (GLIBCXX_CHECK_STDLIB_DECL_AND_LINKAGE_0): Define.

Browse Source 
* linkage.m4 (GLIBCXX_CHECK_STDLIB_DECL_AND_LINKAGE_0): Define.
	(GLIBCXX_CHECK_STDLIB_SUPPORT): Use it to test for lrand48
	instead of drand48.
	* acconfig.h (HAVE_DRAND48): Renamed to HAVE_LRAND48.
	* crossconfig.m4 (*-freebsd*): Define HAVE_LRAND48 instead of
	HAVE_DRAND48.
	* config.h.in, configure: Regenerate.
	* include/bits/stl_algo.h: Use _GLIBCXX_HAVE_LRAND48 to guard
	lrand48 use.
