When using --disable-virglrenderer, QEMU still creates hw-display-virtio-gpu-gl.so hw-display-virtio-vga-gl.so hw-display-virtio-gpu-pci-gl.so but when these are loaded, they provide no functionality as the code which registers types is not compiled in. Funtionally this is relatively harmless, because QEMU is fine loading a module with no types. This is rather confusing for users and OS distro maintainers though, as they think they have the GL functionality built, but in fact the module they are looking at provides nothing of value. The root cause is the use of 'when/if_true' rules when adding sources to the module source set. If all the rules evaluate to false, then we have declared the module, but not added anything to it. We need to put declaration of the entire module inside a condition based on existance of the 3rd party library deps that are mandatory.
