MFC r250545:
  Some filesystems (NFS in particular) do not fill out the d_type field when
  returning directory entries through readdir(3). In this case we need to
  obtain the file type ourselves; otherwise newsyslog -t will not be able to
  find archived log files and will fail to both delete old log files and to
  do interval-based rotations properly.
