True, there is a phase ordering problem. But isn't that something
that can be worked around by making the necessary adjustments to
make(1). The adjustments would be that if .depend is out of
date, it is being made without making any sources that are out
of date (or missing). This may require adding a special source
to the mix of special sources that make(1) already has: .SOFTDEP
or something like that. One can also hardcode this special case,
but that seems ugly.
