After installworld inside the release chroot succeeds, the release.4
target makes one or more crunched binaries, and these throw away some
stuff in the objdir.  In my release object directory, I don't see the
"hostname", etc. which is expected (they are part of these crunched
binaries), but chmod is cerainly here:

$ ls -l /spool/release/usr/obj/usr/src/bin/chmod/
total 256
-rwxr-xr-x  1 root  wheel  10974 Sep 12 19:01 chmod
-rw-r--r--  1 root  wheel   2824 Sep 12 19:01 chmod.1.cat.gz
-rw-r--r--  1 root  wheel   3459 Sep 12 19:01 chmod.1.gz
-rw-r--r--  1 root  wheel   6816 Sep 12 19:01 chmod.o
$ 

The bottomline is that without fixing release.4 you cannot reuse the
release object directory to do an installworld.  Fixing release.4 is
not easy since it reuses some preparatory stuff built by early stages
of buildworld, to be upgrade- and cross-friendly, so just changing
MAKEOBJDIRPREFIX wouldn't work (just verified this).

If you do a "make -DNO_CLEAN buildworld" it won't build exactly the
same binaries as a normal buildworld would do.  This has to do with
the same "bug" that crunched binaries build reuses the same object
directory.

I don't undertstand your question.  After release has rolled, release.[6-8]
have already been built, the contents has been packaged, and you're free
to do whatever you want with your /usr/obj (in the release chroot).
