iOS cross compiling support

[Scott Webster]

Probably this subject would be better dealt with on macports-dev?  Or
at least in addition to here...

Sorry, I have no other helpful comments!

However, it wouldn't be surprised if it was switched to clang for xcode 4. Bottom line: you explicitly pick the target sdk and a compiler in that sdk.
