[Haskell-iPhone] Xcode 5 support for GHC iOS

Hi all, Just wanted to let you know I've finished updating GHC iOS to support Xcode 5. The new scripts are at https://github.com/ghc-ios/ghc-ios-scripts/tree/xcode5 and you'll find updated instructions at http://ghc.haskell.org/trac/ghc/wiki/Building/CrossCompiling/iOS . Please let me know if you have any trouble! Cheers Luke
