gnu: mesa: Re-enable X11 protocol support for the DRI2 extension.
Starting with Mesa 24.3, X11 protocol support for the DRI2 extension is
no longer enabled by default. The developers are phasing it out in
favor of DRI3, and have moved it into an optional 'legacy-x11' feature.
Re-enable it to retain hardware acceleration on older systems that do
not support DRI3.
* gnu/packages/gl.el (mesa)[arguments]<#:configure-flags>: Add
'-Dlegacy-x11=dri2'.
