I think we should enable the machines in the default configs (and maybe
optional devices that are not automatically selected by machines), e.g.:

CONFIG_I440FX=3Dy
CONFIG_Q35=3Dy
CONFIG_VIRTPC=3Dy
CONFIG_ISAPC=3Dy
CONFIG_VIRTIO=3Dy
CONFIG_PARALLEL=3Dy

In configs/nemu (or configs/lean-kvm or however we'll call it), you will
then only have:

CONFIG_Q35=3Dy
CONFIG_VIRTPC=3Dy
CONFIG_VIRTIO=3Dy

Would that make sense?
