Subject: [PATCH] configure: Fix errors in test for__sync_fetch_and_and

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).
