Unfortunately, as far as I remember, this kind of configuration is
necessary to build xdriver_xf86-video-imx-viv. Mesa is necessary to
build GLX support but, EGL/GLes have to be provided by imx-gpu-viv.

However, maybe your idea is correct and xdriver_xf86-video-imx-viv should be 
reworked (but it is not a trivial work).
