[Scip] Examples makefiles in SCIP may eat all personal data (make clean dangerous)

[Tobias Achterberg]

Uuupppss.. that's really BAD! Sorry about this, I guess that is still something that I am 
responsible for.

I strongly suggest to use something like

rm -f $(OBJDIR)/*.o
rmdir $(OBJDIR)

instead. I don't think that the $(OBJDIR) will have subdirectories, and I also don't think 
that there is anything else than *.o files, so this should be much safer.
