This also has "&& TTY" in -next (not actually relevant)

Its weird, but since CONFIG_TTY is not set (see the config), the
HVC_DRIVER symbol is not even visible, so I suspect that the above select
does nothing :-(  But also, I can't see how VIRTIO_CONSOLE could be set
in the first place since TTY is not set.

(cc'ing some more people) (this is a randconfig that has TTY=n,
HVC_DRIVER=n, but VIRTIO_CONSOLE=y)
