Subject: [Qemu-devel] [PATCH] configure: Remove unneeded defines from checks

To: QEMU Developers <qemu-devel@nongnu.org>

_GNU_SOURCE is already defined in QEMU_CFLAGS which
is passed to gcc in shell function compile_prog.

Removing the definition from several checks avoids compiler warnings
(which are now written to config.log).
