Comment(by batterseapower):

 Ian: thanks. The other question is from this point:

   * There is some more opportunity to cut down on the number of exports
 from ghc-stage2.exe. I don't currently prevent libHSghc-prim, libHSbinary
 and the RTS from being exported from ghc.exe, because they are only
 depended on transitively. How can I get hold of their version numbers in
 ghc.mk?

 How do I got hold of the (version numbers/package names including the
 version suffix) of ghc-prim and binary from within ghc.mk?
