qemu-system-x86_64 doesn't actually link against libGL.so when built with this flag, and virtual/opengl pulls in a lot of X11 packages which is not ideal on Wayland. USE=opengl is actually needed on Wayland for the virgl renderer. 8.2.1 and 8.2.2 build successfully and are perfectly functional without virtual/opengl. Thus, we could either: 1) replace the virtual/opengl dependency with media-libs/libglvnd (Theoretically, this is not needed, as the qemu binaries are not directly linked to any libraries provided by libglvnd either) 2) remove the virtual/opengl dependency entirely
