There are no symlinks with MAKEOBJDIRPREFIX.  If you are in the
directory /foo/bar/baz and have MAKEOBJDIRPREFIX set to /usr/obj,
typing "make obj" will create the directory /usr/obj/foo/bar/baz
but no symlink in the current directory.  Then, from make(1):

    rectory exists make will chdir(2) to it.  These actions are taken before
    any makefiles are read which is why they need to be set in the environ-
