[Mesa-dev] mesa/st: how to force glLinkProgram to create/translate the program?

I used to have a patch which precompiles some of the commonly used
shader variants, but I seem to have deleted it because Wine also
loaded shaders on demand and compiling more shader variants than
necessary could only make it worse.
