Conceptually, local should override everything, as it's the "most specific"
information available, but from a technical standpoint, we can't parse the
machine and distro configs until local.conf is parsed, as that's usually
where the MACHINE and DISTRO are set.  You can use a 'local' override to get
around it, or you can ask the distro/machine maintainer to use ?=
assignments (set only if unset).

PREFERRED_VERSION_<package>_local = "xxx" is how you use the override.
