    pango: Don't fail to initialize if LC_CTYPE is not set
    
    g_once_init_leave() does not work on NULL, and just returns... and
    all future calls to g_once_init_enter() will block forever.
    
    Happens on Android, so let's just fall back to the C locale if there's
    nothing else we can do.
