Comment(by tibbe):

 I think we should go in the direction of having all backends available at
 all times (i.e. make GHC a cross compiler.) That way we won't have any
 #ifdefs at all, but only Haskell:

 {{{
 someFunction = case arch of
     X86 -> ...
     X86_64 -> ....
 }}}

 That way the type checker should catch most problems for us.
