Merge pull request #1226 from howbazaar/1.21-fix-jujuc-links

Check the result of the symlink.

When creating the jujuc symlinks, an absolute path became relative by reading the symlink.

While this isn't a cohesive more permanent solution (i.e. sorting out the whole tools relative/absolute malarkey), it does make 1.21 work.
