Add virglrenderer, an optional dependency of QEMU, which facilitates acceleration of rendering and optionally video decode through virtio-gpu. Add an upstream patch to fix the build with glibc 2.43, not present in a stable release yet. Signed-off-by: Joseph Kogut <joseph.kogut@gmail.com> Signed-off-by: Romain Naour <romain.naour@smile.fr>
