Optional glvnd was a complete mess and this isn't happening.

Also, performance impact is only relevant if cpu-bound which is rather
rare for normal games and applications (aka, not stuff like glxgears).
"some" emulators can be more cpu-bound, but a lot of the bigger ones
support vulkan anyway nowadays.

Yes, there are cases where it'd be better but we're way too far from
it being worth the maintenance cost and confusion. Recently seen people
run into issues with libEGL when forcing -Dglvnd=false too, more things
to worry about.
