  AFAIU, dri3 requires xshmfence, and our xshmfence package depends on xorg7. A 
similar condition existed already, so I kept it.

  If someone can get it working without xshmfence (thus without xorg7), they can 
send a patch :-)

  Note that it's possible to select BR2_PACKAGE_XORG7 without selecting any X 
library. By itself, it doesn't actually do anything. Perhaps we should even get 
rid of that option, I don't know.
