GHC 6.12 + zlib + Mac OS 10.6

This was reproduced on rc2, too. I installed ghc-6.12 rc2 by the installer.

As the ticket I mentioned[1] says, The problem is the flags to build
32-bit binaries is not passed to the hsc2hs executable when the hsc2hs
wrapper get any --cc parameter. Cabal passes --cc parameter to the
wrapper to tell where gcc is. So when building a package with Cabal,
hsc2hs goes wrong.
