GLES ES 3.0 Support Panfrost

I get this error:
[brent@pinebook-pro ~]$ MESA_GL_VERSION_OVERRIDE=3.3 MESA_GLSL_VERSION_OVERRIDE=330 supertux2
terminate called after throwing an instance of 'std::runtime_error'
what(): locale::facet::_S_create_c_locale name not valid
Aborted (core dumped)

This can happen when your locale has not been generated properly.

Run `locale` to find your current locale.

You need to edit /etc/locale.gen, uncomment the line for your locale, then run `sudo locale-gen` to update the locale data.
