For example, when I wanted to try out the framebuffer EGL backend of the 
eglvivsink element in gstreamer-imx , I had to modify the 
gpu-viv-bin-mx6q.inc file to force it to not install the X11 binaries. 
(Same when I tried to develop a directfb EGL backend, which I postponed 
for now, because there are zero docs and examples on how to actually do 
this.) I will also need it later, when I start working on the Wayland 
backend. I also needed it when trying to build an xbmc fork with imx 
extras ; it can only render to framebuffer, not to X11.

I agree though that a switch-like statement would be better, but I am 
not sure how to implement that properly (my OE foo is not that high :) )
