[Haskell-iPhone] Can anyone help me test GHC-iOS compiler?

I tried this — building GHC HEAD configured to use the native code gen, and
then building the cross compiler using that, and got the same errors as
everything else thus far:
10.9 Mavericks is likely coming out in less than a month, along with iOS7
and Xcode5 final, so it's definitely worth sorting this out!
Not quite sure what to try next though...
