IMHO not an entirely unusual situation in other places of the kernel,
eg. one can enable USB devices, w/o having an usb host adapter enabled.
And even if some USB-HA driver is enabled, the actualy machine doesn't
necessarily have the corresponding device.

So, all virtio devices should depend on TRANSPORT_A || TRANSPORT_B ||
TRANSPORT_C || ... ? (and also change all these places if another
transport is added) ?
