  * Separate the OS/Arch classifiation used for different purposes
  We have to classify System.Info.{os,arch} strings into the OS and Arch
  enums. For that purpose we have to be quite permissive since there are
  lots of ailases that the various Haskell implementations use. However
  for parsing os and arch names in .cabal files we'd prefer to use
  canonical names, though we do have to allow the couple aliases already
  in common use.
