Would it be worth transferring that comment into the building guide (a cross-compiling page perhaps). The distinction is subtle and the information is useful

There is http://hackage.haskell.org/trac/ghc/wiki/CrossCompilation but I'm not sure it has this info

Oh yes, I plan to fix the wiki. It needs more than just an update for this change though... the CrossCompilation page is really a design document, not a user guide, we need some proper documentation. Cheers, Simon
