localization: finish up with getting message catalogs building

There are still some issues here - specifically with the C
dtbuilder/dtcodegen catalogs.  They may be broken due to dtbuilder not
being built yet.

Also, once dtinfo can be built, the msgs and app-defaults for it
should be re-enabled.

I also see gencat coredumping in localization/ while doing a multicore
(-jX) make.  Regular single core builds seem to work fine.
