[Qemu-devel] [PATCH 06/11] configure: Fix errors in test for__sync_fetch_and_and

[Peter Maydell <peter.maydell@linaro.org>]

From: Stefan Weil <sw@weilnetz.de>

The old test code raises two compiler warnings which are errors since
commit 417c9d72d48275d19c60861896efd4962d21aca2.

These errors could result in compilations with compiler flag
-march486 (so all nice features of newer processors got lost).
