This is correct and how ln works. Since the first argument is not
absolute, it is relative directory of the link name. In other words,
/tools/bin/tclsh will link to a tclsh8.4 in the same directory, which
happens to be /tools/bin/tclsh8.4. By not making the first argument an
absolute path, it means that we could just mv tclsh and tclsh8.4 to a
different directory and the symlink would still be correct.

I suggest reading the ln man page and playing around with the
different forms of links. It's a strange beast at first.
