Why would we want to avoid failing the build if we don't have msgfmt?

I understand why you'd want NO_GETTEXT in that case, but what's the
point of building with NO_GETTEXT= NO_MSGFMT=Y?

If we can't build the *.mo files we'll have a completely broken
installation that can't do anything useful with gettext, so why not just
build without gettext at that point?

When this patch is applied a lot of things related to gettext in our
tests fail if you build with NO_GETTEXT= NO_MSGFMT=Y, because those
things are assuming that if NO_GETTEXT isn't defined we'll have the *.mo
files, po/build etc.
