That output comes from qemu-options.hx, which contains information
added by hand. That means that some machine options end up there, some
don't. If this is only supposed to contain common options, we should
remove s390-squash-mcss (and the -key-wrap ones are s390-specific as
well).

Indeed. This contains the real set of properties and does not depend on
whether a developer added some extra help text.
