Yeah, thought about that. But then the test is skipped if
gnutls-available-p returns nil. What happens if I believe that I have
configured and build Emacs to include gnutls, but, for some reason it
isn't. The test will be skipped when it should succeed.

The same is true for all the other conditional features.

I wonder if we need a "conditional feature" test selector.
