Actually, it should, but the syntax used in the metaunit to
generate that
part of Configure (Loc.U) us *only* used in Loc.U, and I
have not found
either the documentation of that syntax, nor a reason why
tail is not put
inside the list in Configure.
The list that should be probed is:
awk cat chgrp chmod chown comm cp echo expr find grep
ls mkdir mv rm sed sleep sort tail touch tr uniq
The list that ended up in Configure:
awk cat chmod comm cp echo expr grep ls mkdir rm sed
sort touch tr uniq
Why chmod, but not chgrp and chown? Why grep, but not find?
Why rm, but not mv?

I know why they are there. I just cannot explain (yet) why
they are not
initialized.

And if you want a more generic approach, you can create a
Policy.sh and put
the defines in there, so you do not have to add all the
-D.... to Configure
all the time.
