Right, but then a patch adding "make target-clean" should also be
responsible for adding the appropriate documentation :-)

Not that much: any optional dependency in Buildroot will exhibit
exactly the same behavior, and there are hundreds if not thousands of
places were we rely on optional dependencies.
