Nevermind this last point, these suggestions are functionally identical;
the AMDEP conditional also only handles the "explicitly disabled" case
and is defined almost exactly the same way as NO_DEPS above (test is
just reversed).

So there is no reason to use #1 except to save a line in configure.ac.
