It does what it says. It builds VM which are not linking against
OpenGL, nor using OpenGL headers.
It assumes that the system does not have an opengl library installed.

Certain plugins (like B3D plugin) depend on opengl. But you can build
it as external plugin,
so it could still depen on opengl (and fail to load if system where
you run vm doesn't have opengl library installed)
But VM itself no longer depends on having opengl library, which makes sense.
