Thanks for feedback!

But for om-gta01 we use swrast, for gta02 swrast and glamo, so it needs
to be machine specific here, or I'm missing the point :/.

And what about different virtual/libgl providers? It will be even more
hackish magic to check if all machines are sharing the same provider or
not IMHO.

BTW: already pushed change from machine overrides to distro overrides,
then I was able to build gta01 image fine, but still not very happy with
it.
