[OCaml] Generate documentation again with autoconf buildsystem.

Patch by Evangelos Foutras:

r220899 started using ocamlfind to build the OCaml bindings but
docs/Makefile still contains references to the OCAMLDOC macro which
is no longer being defined. The result is that OCaml documentation
isn't generated/installed.
