Hmmm, so it will attempt to build them as part of the ghc tree?

Greencard has two sets of makefiles - those used inside the ghc tree and those 
used in distributions.  I've been focussing on the latter and was planning to 
remove the former.  Basically, if the ghc code doesn't depend on greencard, 
and the ghc distros don't include greencard, there's no reason to provide and 
maintain those makefiles.  

This is (almost certainly) the reason for the reported failure today (Peter 
Simons: "problems building ghc-current").
