installworld fails in usr.bin/tip/tip

web diary, but he seemed to have no time to track this down or submit
the report to bugs@]

Recently, cu(1) has been replaced by tip(1). However, since cu is installed
with schg set on older system, creating a hard link from tip to cu is
refused and install fails. Looking at other Makefile's, removing schg in
beforeinstall target seems to solve the problem.
