configure: Add configure-time check for GCC 4.0+ atomic built-ins.
We found out earlier that GCC sometimes produces an error only at link time
for atomic built-ins that are not supported on a platform. This actually
tries the link at configure time and should thus reliably detect whether
the atomic built-ins are really supported.
