Looks great!

Tried a while ago with the following setup:

* --tagret=ia64-unknown-linux-gnu
* "Stage1Only=YES"
* host compiler is ghc-7.6.1 (unregisterised build)

to get real cross-compiler and found out the following issues:

mkGmpDerivedConstants is built for target and ran on host
[attached patches for it]

make install fails as it 'forgets' to install proper ghc-pkg in
$(${cross}-ghc --print-libdir)/bin/

But the resulting cross-compiler was able to build working hello world!
