Okay, I just accidentally created conditions for this error on my
system...  I checked in a change to newvers.sh while a buildworld was
running, which led to a situation where newvers.sh was newer than
osreldate.h at the end of the buildworld.  Then an installworld tried to
regenerate osreldate.h due to its dependency on newvers.sh, which would
fail if the obj was readonly at that point.

I think we could see if something similar applies for you if you use
this command:

  make -dm installworld SUBDIR_OVERRIDE=include

And we'd be looking for the end of the output to be something like:

The "env: not found" is what I got instead of a permission denied, and
probably has something to do with me cross-building amd64 10.0 from an
i386 8.x machine.  I think that's where you'd see the permission error.

If the same sort of thing is happening for you, then all that's left is
to figure out why osreldate.h is out of date at install time, and how to
handle things if that's the case.
