[PATCH] drop -q flag when using grep


We don't currently want to rely on the -q option to grep.

Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-10-23  Mike Frysinger  <vapier@gentoo.org>

	* configure.in (libc_cv_gcc_static_libgcc): Drop -q flag to grep and
	send the output to /dev/null.
	(libc_cv_cc_with_libunwind): Likewise.
	(libc_cv_as_noexecstack): Likewise.
	* configure: Regenerate.
