Boards that do not include an USB controller should not provide USB devices. However, when running "qemu-system-s390x -device help" for example, there's still a usb-hub, usb-kbd, usb-mouse and usb-tablet in the list of "supported" devices. Let's fix that by compiling and linking the USB files only if it is really necessary. Signed-off-by: Thomas Huth <thuth@linux.vnet.ibm.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
