 Yes, I've done that :-)

 Note that in Config.in this is *not* the case now: GLX depends on
BR2_PACKAGE_MESA3D_DRIVER, not on DRI. So it is currently possible to configure
mesa3d with a gallium driver and enable GLX, and this will pass -Dglx=dri to
meson. I don't know what kind of fireworks that that will give...
