That did the trick.

I somehow stumbled upon 
https://ghc.haskell.org/trac/ghc/wiki/Attic/Building/BuildSystem/New, 
and was using that as a guide.  It looks like I missed reading 
https://ghc.haskell.org/trac/ghc/wiki/Building/Modifying, where 
BUILD_DIRS is documented.  My bad.

Thanks for the quick response.

Chris.
