mongodb: disable support for armv4 and armv5

When compiling for armv4 or armv5, we get the following error:

src/mongo/util/signal_handlers_synchronous.cpp:188:9: error: 'current_exception' is not a member of 'std'
     if (std::current_exception()) {
         ^

This is because libstdc++ will only enable std::current_exception if ATOMIC_INT_LOCK_FREE > 1, which is not the case for armv4 and armv5 architectures, so disable them.
