  * difficulty:  hard => easy (<4 hours)

Comment:

 Implementing this just for ghc 6.8 and later should be easy since we can
 parse the output of ghc --info to find the:

 {{{
  ,("Have interpreter","YES")
 }}}

 read the output of {{{ghc --info}}} at type :: [(String, String)] and
 lookup the key "Have interpreter" and check the corresponding value
 against "YES" / "NO".

 That should be used to set the default of whether ghci libs are built or
 not. Perhaps if the user explicitly asks for them and they cannot be
 supported there should be a warning.
