I didn't have an immediate practical reason for it beyond just not
leaving holes in the dependency DAG.
But yes, nothing is only building bin-wrappers/% now, so nothing needs
this. It just helps to not have to worry about Makefile targets not
needing other targets to work.

Or wget depending on your router being plugged in? Beacuse that's what
you use it for?:)
I get the general point, but I don't think these are comparable to those
sorts of loose or semi-loose dependencies. For repack it'll service up
e.g. "-h" without pack-objects, at least that's something...
Whereas these scripts all end with invoking the binary corresponding to
their name, so they really are useless without that target. So I think
it makes sense to make it a dependency of the target in the Makefile.
