I just noticed that this patch breaks the feature detection mechanism,
after it is applied it is back performing all tests at every make call,
this needs rethinking, so I'm dropping both.

Ingo, please disregard, yet again, my latest pull request, sigh.

Jiri, this could be something for tests/make, till then I'll try
to check this manually.
