Log Message:
Multiple cleanups:
- Move PKG_INSTALLATION_TYPES where it belongs.
- No need to use GNU make.
- No locales provided, so remove USE_PKGLOCALEDIR definition.
- Add a note telling that the usage of bsd.options.mk in this package is
  a hack and should be fixed (i.e., splitting the package in different
  ones).
- Get rid of the ugly PLIST handling.  (Anyway, the 'new' solution, based
  on PLIST_SUBST as usual, has to go away when the previous point is fixed.)
- Reword DESCR, based on the included README.
- Install info file correctly and bump PKGREVISION to 1 because of this.
