No they won't: If Setup.hs builds then it's installed, and besides, we
don't need it any more if we've already built Setup. So there's no point
in Setup.hs checking it's installed (which is the effect of adding a dep
in the .cabal file, which I assume is what you meant).

Can you please point me at the shared policy that means that base and
Cabal are always available? I'm sure we could add filepath to it.
