It wasn't easy, but I got it to build[1]. I hope that helps. It adds
both virgl_renderer and virgl_renderer_next. I think virgl_renderer
is on by default with --gpu, and virgl_renderer_next is used with the
--gpu-render-server argument. Hopefully at least one of those does the
right thing — let me know!
