Okay, the attached patchset implements the change of --with-gettext
to an automatic option: if nothing is given and detection fails,
use of gettext will be skipped. If user has given --with-gettext and
detection fails, configure will abort.
As a safety net, --without-gettext is still around that will enforce
that gettext is not used.

Please review.

Making that mandatory was a short-sighted mistake. The new approach
should be better.
