Although intltool forks gettext's build system, it behaves quite
differently:

 * .po files need to be updated manually, either with

  * 'make update-po' in a configured directory where srcdir==buildir

  * either with::

   'intltool-update --pot && for i in *.po; do intltool-update ${i%.po}; done'

 * The .pot file isn't included on 'make dist'
