Hmm, I'd rather not add a --force to anything. Where else would you want
Ideally we would just do whichever bits of re-configuring that are
necessary. With a dependency framework this should be quite possible as
we could treat each field in the .cabal file as a separate bit of info
with it's own timestamp etc.

How about just re-running configure if we think it's necessary, and
using the previous configuration flags?
