The Makefile section you noticed uses the code from this project:
http://ocaml-coverage.sourceforge.net/
However, it has remained unused for years. In order to compile said
project, I add to patch the generated Makefile this way:

--- Makefile	2012-07-25 16:26:18.653952714 +0200
+++ Makefile	2012-07-25 16:21:22.693155350 +0200

However, I did not test the result, I just made sure it compiled. So I
cannot give you much more information than this.

HTH,
