Debated adding a warning, but feel that the noise isn't overly
necessary (speechd is still default, would have to go out of
your way to have no backends).
Tests still pass with neither set, and in theory shouldn't cause
problems for revdeps given the mock/silence backend is still usable
if any applications tries to use it and all the same headers are
installed for building.
