I think they were just intended as a convenient shortcut to allow
updating the cloned trees (which are otherwise not automatically
updated). I'm not sure how useful they are in practice.

It looks like my build scripts use "make -C tools $FOO-force-update", so
removing them would be a problem for me personally.

On the other hand since they are only for use by end users and not
dependencies of any other rule I suppose we could just nuke the
conditionals but leave the rules themselves?
