Revert "Remove ocaml/.depend from git."

This reverts commit 064569bcbf.

This commit does the wrong thing: creating an empty ocaml/.depend
file is wrong because building the OCaml bindings will fail.
Not having this file will prevent automake from running.  Therefore
this file has to exist with the correct content in git.
(cherry picked from commit e3acf93ce9)
