flag to chown to change the symlinks themselves instead of their targets.
Also change permissions of all symlinks, so they don't depend on the umask
during make build.

The installer will create these directories during install.
So local setups will not get overwritten during upgrades.

So remove that option, which is just a remainder of old times when
malloc used to hold on to pages. ok stefan@

this should fix the problem with random ntpd(8) deaths.

and add prereq targets, so some header files are generated by BUILDUSER
during 'make prereq' instead of by root during 'make includes'.
Switch the order of 'make cleandir' and 'make includes' during 'make build'
so we don't generate many files twice.
Except for some machine@ symlinks from ${MACHINE}/stand, /usr/obj is now
clean from files generated by root during 'make build'. Those will be
cleaned up in a second step.
help, testing & ok deraadt, input from natano, further testing rpe

C11 6.5.6.9 says:
When two pointers are subtracted, both shall point to elements of the
same array object, or one past the last element of the array object; the
result is the difference of the subscripts of the two array elements.
In these cases the objects are arrays of char so the result is defined,
and we believe that the report is based on a compiler incorrectly trapping
on defined behaviour.

- If you start make build as root, everything will be run as root.
Nothing new here. New is, that you can set BUILDUSER=somebody and the
unprived parts will be run as somebody.
- If you start make build with sudo, the unprived parts will be run as
the real user (meaning YOU). You can still set BUILDUSER=somebody and
the uprived parts will run as somebody.
- If you start make build as a normal user it will error out. "I'm sorry
Dave."
Note that DESTDIR must be on partition with the noperm flag set for make
release to work correctly as an unprivileged user.
