The reasoning for the change is that glvnd is a thing.
Maybe the drivers you mention should just use that.
Recent distros enable glvnd in Mesa out of the box and
NVIDIA also supports that.
qemu unfortunately doesn't work this way. It links directly with
libgbm, and libgbm probes directly into the drivers. This are the
errors:

failed to bind extensions

qemu-system-x86_64: egl: render node init failed
And this is where they happen:
Thread 1 "qemu-system-x86" hit Breakpoint 1, 0x00007ffff77e6020 in

This looks like it's coming from a mesa-native build
which should match the target build version.
The problem may be that despite of this, it tries to open
the host drivers from /usr instead of .../recipe-sysroot-native/usr.
