Hey! I'm already working on this! :-)

Are you on IRC? There is a very lengthy discussion on this topic right
now in the #buildroot channel. This would have been a nice occasion to
properly sync-up our work, and to avoid duplication...

(adding Paul in Cc, who's been very helpful on IRC on this topic.)

But anyway, this patch should be split in two:
  - a first patch to add the virtual package itself
  - a second patch to make mesa3d a provider to the virtual package

Strange how this is so similar to what I've done here! Hehehe! ;-)
