you asked for language called 'garbage'
$ LANG=garbage grass70
...
Failed to set LC_ALL to garbage.UTF-8 (unsupported locale setting)

it indicates that there is no such locales on your system. So far
seems to be something what I would expect.

Changing language settings in wxGUI preferences to 'de'. Since I don't
have german locales on my system, it fails for wxWidgets.

Failed to set LC_ALL to de_DE.UTF-8 (unsupported locale setting)

The rest of GUI starts in german, since po files for 'de' are
available. I am not sure what you mean by mess you are referring to.
Probably you are point out that major part of GUI is localized (comes
from GRASS po files) and minor part (wxWidgets) is kept in system
locales. We have three options:

1. keep current behaviour
2. if setting LC_ALL fails then go back to system settings (don't use
GRASS po files).
3. fix settings wxWidgets locales even if locales are not available.
