Fix some minor issues and re-enable building of DE, ES, FR, and IT locale data (help and message cats)

Note, there are still some issues with certain programs appearing not
to use their localized message catalogs properly, while others work
fine.

Also, in order to build these now, you need to make sure you have
installed the DE, ES, FR, and IT locales before building or you will
get failures.  On [k]ubuntu, at least, you can install these with the
following commands:

sudo locale-gen de_DE
sudo locale-gen es_ES
sudo locale-gen fr_FR
sudo locale-gen it_IT
