	* config.make.in (gnu89-inline-CFLAGS): New variable.
	* Makeconf (CFLAGS): Evaluate that one instead of hard-coding.
	Suggested by Olaf Buddenhagen,
	<http://lists.gnu.org/archive/html/bug-hurd/2007-11/msg00006.html>
	* configure.in (libc_cv_gnu89_inline): Fill depending on a compile-time
	test, as per glibc HEAD, 2007-11-07.
