    Use atomic operations routines that are implemented entirely
    in C by locking interrupts. Selected by architectures which either
    do not have support for atomic operations in their instruction
    set, or haven't been implemented yet during bring-up, and also
    the compiler does not have support for the atomic __sync_* builtins.
