glog can optionally use atomic __sync built-ins. However, its configure script only checks for the availability of the 4-byte variant, but the code also uses the 1-byte variant. While this works on most architectures, it does not on architectures that implement only the 4-byte variant, such as Microblaze. So if the architecture does not implement the 1-byte variant, we hint the configure script that atomic built-ins should not be used.
