                         disabled then some platforms will attempt a
                         "system" install by placing default values to
                         be placed in a system location other than

        NOTICE: configure was unable to determine the architecture

        Qt will not use a specialized implementation for any atomic
        operations. Instead a generic implemention based on either GCC
        intrinsics or C++11 std::atomic<T> will be used (when
        available). The generic implementations are generally as fast
        as and always as safe as a specialized implementation.

        If no generic implementation is available, Qt will use a
        fallback UNIX implementation which uses a single
        pthread_mutex_t to protect all atomic operations. This
        implementation is the slow (but safe) fallback implementation
        for architectures Qt does not yet support.
