If in doubt, recompile.

that's a long open ticket for cabal, and I'm not keen to duplicate that
for xmonad.
 
we have a simple policy: look only at xmonad.hs, and compile if it
is out of date. that's the only rule. anything else is duplicating
--make and chunks of cabal in an ad hoc way.

having smarter recompilation checking is not an issue i feel we have to
solve, but we can lean on the cabal and ghc guys to improve things at
their end.
