Remove the configure notice about unknown architectures

With 5.7, we can rely on c++11 atomics (or the msvc ones), so
the note doesn't make sense anymore.

-        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.
