[Haskell-iPhone] cabal arch function

[Stephen Blackheath [to GHC-iPhone]]

Stefan,

The short answer is that there is more work to do on Cabal. I didn't get 
much further than the changes necessary to compile plain Haskell packages.

At the moment I'm putting the priority on getting the stuff that's 
already done integrated into the mainline (ghc in particular). I am 
intending to get to that work soon.
