The version of VA-API (0.35) could be kind of generated throughout the
patchset. 0.36 API version is due out soon, but a 0.36 libva should
accept 0.35 drivers. I would still recommend you to auto-generate all
those instances of 0_35 though, not necessarily auto-detected, but
definitely generated from a single location.
