[Haskell-cafe] Cross ghc-7.8.3 for PowerPC build fails

[Karel Gardas]

Considering that cross-compilation is a little-bit on bleeding edge 
still I would recommend to use common 32bit PowerPC host first to build 
and *test* GHC to know there is no outstanding issue. Then, when you 
know PPC NCG is in a good shape you can continue with cross-compilation 
attempts...
