[Haskell-iPhone] iOS cross compile instructions now on GHC wiki / progress update

[Stephen Blackheath [to GHC-iPhone]]

Alex,

I can't help much because I'm even more confused than you are about 
subprojects on the ghc-ios repos. Try this:

1. Clone your http://github.com/ghc-ios/ghc repo locally to give 
yourself a clean checkout.
2. Go into it and check out the 'master' branch: git checkout master
3. Point the 'origin' remote at the central ghc repo.
4. Now do
   ./sync-all --no-dph get
   (This will get the stock standard subprojects, just exactly how 
things would work for a normal ghc checkout from ghc HQ.)
5. Now back to the branch: git checkout master-merge-ios
6. Now you can point 'origin' back to ghc-ios/master-merge-ios again if 
you want.
7. Follow the rest of the build instructions.
