ahh, if glvnd moves on to try the next driver after the first one
fails, that would work perfectly.  Not sure if I'd remove the code
from mainline but might hide it behind a debug flag.  Haven't thought
it through too much yet, since I assumed it would require teaching
glvnd new things.  But it would be nice to worry less about breaking
things that aren't in CI and not easy to test.
