Comment:

 The problem here is not that GHC's Binary library has an instance for
 `Int`, it is that Haddock uses GHC's `Binary` library at all.  GHC's
 `Binary` library is for serialising interface files, and since interface
 files can be platform-specific it doesn't matter that we have a platform-
 specific instance for `Int`.

 I think Haddock should either use a local copy of Binary with a platform-
 independent serialisation format (like it used to! :-) or it should use
 `Data.Binary`.  The latter adds a new dependency to GHC, but in the long
 run that's not a disaster.  For a quick fix, the former solution will do
 fine.
