[Qemu-devel] [PULL 44/54] vhost-net: compile it on all targets that have virtio-net.

[Paolo Bonzini <pbonzini@redhat.com>]

This shows a preexisting bug: if a KVM target did not have virtio-net enabled,
it would fail with undefined symbols when vhost was enabled.  This must now
be fixed, lest targets that have no virtio-net fail to compile.
