It *is* a build tool, indeed. Build tools aren't special, everything
in the set ${PATH} can be a build tool. Install tools are a smaller
set of specifically listed tools. It's not used during an installworld;
when you see an attempt to use touch(1) during the installworld, it's
a sign of a broken buildworld (forgot to run it, clock ran away, etc.).

Very good, I like it.
