I'm confused.  I thought we copied the configuration from the target to the host 
as part of the bootstrapping process, but now I can't see how this is supposed 
to happen for HsBaseConfig.h.  It looks like following the instructions in the 
building guide will result in failure if you try to cross-compile between 
machines with different word sizes, but I know I've done this in the past :-/
Ian, any idea how this is supposed to work?

Anyway, to answer your question, using hsc2hs in System.Posix.Types will cause 
problems for bootstrapping GHC, yes, because we can't run hsc2hs on the target 
without GHC, but we can run configure.  I suppose we could add a dependency on 
another Haskell compiler just to run hsc2hs, but that's a pain.
