relation-graph symlink broken

[turbomam]

In Ubuntu Linux 20 now, but I think I saw this in MacOS 11 too.

make bin/relation-graph

... relation-graph-1.1/bin/relation-graph.bat ln: failed to create symbolic link './relation-graph': File exists make: *** [Makefile:56: bin/relation-graph] Error 1

$ ls -l bin/

total 4560 -rwxrwxr-x 1 mark mark 4661320 Oct 19 14:12 rdftab -rw-rw-r-- 1 mark mark 1 Oct 19 14:10 README.txt lrwxrwxrwx 1 mark mark 1 Oct 19 14:10 relation-graph -> ''$'\n'

This fixes it

cd bin/
rm relation-graph 
ln -s ../relation-graph/bin/relation-graph

I think this supersedes #11
