Couldn't / sholdn't this check be replaced by the new check you introduce?

That seems like a reference to some (internal Suse?) bugtracker? To me 
it is https://bugzilla.redhat.com/show_bug.cgi?id=817187 , but I guess 
https://savannah.gnu.org/bugs/?35880 is the best reference.

I'm +1 for the principle, but does it really work for real world locales 
like de_DE which will use de.mo on runtime?

I would guess that it also should handle all the logic in gettext.c 
grub_gettext_init_ext() and grub_mofile_open_lang() and how these 
functions are invoked: .gz extension, _CC stripping and 
primary/secondary locale_dir.

(I would prefer if all this processing could be done in mkconfig instead 
of on runtime, but I guess the desire for backward compatibility 
prevents that.)

(It also seems to me like the current system lacks support for fallback 
from address@hidden to ll_CC and ll. I don't know if that is a 
real problem.)
