Subject: [PATCH] egl: Add workaround for Mesa <= 22.2
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Older Mesa versions with EGL headers missing the change from
https://github.com/KhronosGroup/EGL-Registry/pull/130
pull in Xlib headers, causing build issues.

This notably happens on the Debian 11 CI image, which until now does not
build the shared EGL code due to missing GBM dependencies. That will
change in the following commit, thus include a workaround.
