Yes and no. The assumption with the version checks is the the tool is present
on the base system (which might be invalidated by build options or install root
pruning) and doesn't necessarily need to be rebuilt. It's an optimization that
works in most, but not all cases.
This is why make in /Makefile has testcases to ensure that it can bootstrap the

In the simple case yes, but not in our case. Our case involves making fixes to
ctfconvert, without bumping the osreldate, because we've forked FreeBSD at a
particular point in time. ctfconvert is not compatible between the build host
and the src checkout, so our ctf data gets corrupted when the host copy of
ctfconvert gets run on the binaries.
