Yes, https://patchwork.freedesktop.org/patch/166596/
worked in past but does not work anymore with latest version
maybe a regression or may be it will work with meson.
irrespective of what/where gets fixed, this patch helps us to move

For rpi layer, I have fixed it like this
https://github.com/YoeDistro/meta-raspberrypi/commit/46dbdbb1f9059dcd36e032a074023ac9c78be4aa

probably, that fix should be made to main mesa-gl recipe itself so all
can use it.
