[Haskell-iPhone] Here's exactly how to build the master-merge-ios branch

[Stephen Blackheath [to GHC-iPhone]]

All,

I have tested it, and it works. During installation it failed saying 
that some file libffi-6.dll doesn't exist. I fixed it with a touch command:

touch 
/Users/stephenblackheath/install/usr/local/ghc-ios-steve/lib/ghc-7.7.20130328/rts-1.0/libffi-6.dll

Then re-did 'sudo make install'

Looks like the makefiles are a bit poked on mainline at the moment.
