Thomas Petazzoni 8df95843ed glog: fix atomic built-in problem
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.

Fixes:
