GRASS doesn't start with non-system locale

[annakrat]

When setting different locale, GRASS session doesn't start:

Traceback (most recent call last):
  File "./bin.x86_64-pc-linux-gnu/grass77", line 2204, in <module>
    main()
  File "./bin.x86_64-pc-linux-gnu/grass77", line 2082, in main
    message(_("Starting GRASS GIS..."))
NameError: global name '_' is not defined

Appeared after ​2246f5b.

To reproduce the issue it is necessary to set language override to some language with unsupported locale.

Thus the full output is:

Failed to enforce user specified language 'ru' with error: 'unsupported locale setting'
A LANGUAGE environmental variable has been set.
Part of messages will be displayed in the requested language.

windows 10 box with german locale, switching winGRASS to english, wxGUI starts, though some warning:

Error: Reading settings from file <C:\Users\myuser\AppData\Roaming\GRASS7\wx> failed.
                Details: not enough values to unpack (expected 2, got 1)
                Line: ''

switching to ru, wxGUI starts and the GUI is partly in russian, though the same warning:

Error: Reading settings from file <C:\Users\myuser\AppData\Roaming\GRASS7\wx> failed.
                Details: not enough values to unpack (expected 2, got 1)

Replying to hellik:

but that's before the commit that caused this

[annakrat]

Looks like it happens on Mac without special locale setting
