Previously, the script only generated the parent CPU and any versions
that had a defined alias. Now generate all CPU versions. Any version
that had a defined alias will continue to use that alias, but those
without aliases will use the generated name $BASECPUNAME-vN. This
generated name will be used as an alternate name for those CPU versions
with defined aliases.
