+ibacm: support distros with older versions of gcc
+
+ibacm implements atomics using gcc intrinsics that were introduced
+in gcc 4.1.2. If an older version of gcc is used to compile the
+code, an error results. Check that the required atomic calls are
+supported, and if not, provide our own implementation.
+
+This fixes a build issue on RH 5.x.
