>    state_tracker: allow to utilize GLSL workaround for broken apps in Gallium
>    
>    Currently Gallium has no way to activate the
>    'force_glsl_extensions_warn' workaround that allows
>    buggy apps that use GLSL extensions without asking for them to work.
>    
>    Since gallium mesa state tracker is essentially split into two,
>    (dri (src/gallium/state_trackers/dri) and mesa (src/mesa/state_tracker))
>    and only former has access to driconf options while later knows nothing
>    about dri, I added this support by reading an environment variable.
>    
>    export force_glsl_extensions_warn=true
