BUG: Correct some of the dependency analysis code.

- Make sure the original link line is untouched
- Avoid duplicating the link line when supporting version < 1.4
- Make sure the cyclic dependencies and such are output correctly in
  complicated cases.
- Avoid outputing dependencies that are already satisfied on the original
  link line when possible.
