Why do they seem wrong. The intent is that you’d only build these tools when
you are cross building. A long time ago, they were in the bootstrap path, but
every FreeBSD system for a long time now has adequate versions of them.
If that’s not the case, then we perhaps need to revisit the logic here. If we’ve
suddenly started needing newer versions, that should be expressed in the
logic as well.
