  * Reimplement createDirectoryIfMissingVerbose to use sensible file permissions
  Hopefully should fix ghc ticket #4982.
  The problem was permissions on directories: previously we used ordinary
  createDirectory and on unix this creates dirs using the current user's
  umask. If the root user has a silly umask then someone doing sudo
  install will end up with dirs that are not readable by non-root users.
  So the solution is to do the same as we do with files: override the
  umask and explicitly set the file permissions based on the kind of
  file: ordinary file, executable file and now also directory.
  Sadly we also had to re-implement createDirectoryIfMissing to use our
  new createDirectory wrapper function.
