Yesterday I took a look at this issue and the problem was that the
installed locale during these calls to gettext was the default one: C.
I've attached a patch that fixes this and now the installer shows
language names in the language itself.

Nonetheless, it didn't work when I removed the call from installer to
installer-real, as the there comment says, and set the locale directly
in the line added by the patch.  Therefore I need to take a deeper look
into libc code to really understand what's happening there, and check if
it is possible to remove that extra call in the future, or find a
satisfactory explanation at least.

Happy hacking!
