Comment 17 for bug 1755912

I meant the option --enable-opengl and, for old versions, --enable-gtk-gl. I know it is required to use virtual machines using Intel GVT-g with dma-buf, and is a option strangely absent from QEMU configuration from Ubuntu's build. Without it, virgl fails too, making virt-manager have an option that does not work (under Spice Display, OpenGL option does not work).

The 2.12 build does crash when tested. That while loop is pretty efficient to trigger it. The git version can keep running it for hours straight with no problem, while the problematic versions crash in seconds.

As QEMU configuration is a result mixed between packages found automatically and those manually set by me, here is the configure command and its results from my QEMU build: https://paste.ubuntu.com/p/z9vnFdTnkD/

Please note that I had no need to build other targets for my use, so the configuration is much smaller than the one used by Ubuntu's QEMU.
