* 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.
2012-10-24 Joseph Myers <joseph@codesourcery.com>
* io/ftwtest-sh (tmp): Define to ${objpfx}io, not using `pwd`.
