I think this will not work because each makefile line is run in a separate
subshell. I've tested the following and it works okay:

install-exec-hook:
        cd $(DESTDIR)$(libexecdir) && for i in $(check_tcp_programs) ; do ln
-sf check_tcp $$i ; done

Also, I've noticed that in SunOS 5.6 and SunOS 5.8:
$ cd /tmp
$ touch afile
$ ln -sf afile alink
$ ln -sf afile alink
ln: cannot create alink: File exists

Which I'm sure is not correct behaviour. To overcome this, can the links be
hard links?

install-exec-hook:
        cd $(DESTDIR)$(libexecdir) && for i in $(check_tcp_programs) ; do ln
-f check_tcp $$i ; done

Or add an rm before the ln -sf?

install-exec-hook:
        cd $(DESTDIR)$(libexecdir) && for i in $(check_tcp_programs) ; do rm
-f $$i ; ln -sf check_tcp $$i ; done
