Don't.  It's not really going to work.

The makefiles of the doc tree set DOC_PREFIX to ${.CURDIR} as you have
noticed already.  The value make(1) gives to this variable is the `real
path' of the directory:

	% cd /tmp
	% mkdir foo
	% cat > foo/Makefile
	all:
		@echo ${.CURDIR}
	^D
	% ln -s foo bar
	% cd bar
	% make
	/tmp/foo

If you don't explicitly set DOC_PREFIX the makefiles will try to
`discover' its correct value by using the real path of the current
directory.  This will not work for symlinked directories.

By setting DOC_PREFIX to /usr/doc you turn off the lookup of symbolic
links and it all works again.
