Bug 1204400

Description of problem:
I cannot link to ocaml-config-file using ocamlc, or load it in the toplevel.
ocamlopt works fine.

Version-Release number of selected component (if applicable): 1.2-3.fc22
How reproducible: always

Steps to Reproduce:
1. sudo dnf install ocaml-config-file-devel
2.
$ cat >x.ml <<EOF
open Config_file

let () =
  let group = new group in
  group#add (new int_cp ["intfield"] 0 "a field of type int");
  group#write "/dev/stdout"
EOF
$ ocamlfind ocamlc -package config-file x.ml -o x -linkpkg
$ ocaml
# #use "topfind";;
# #require "config-file";;

Actual results:
From ocamlc:
File "x.ml", line 1:
Error: Cannot find file /usr/lib64/ocaml/config-file/config_file.cmo

From ocaml toplevel:
/usr/lib64/ocaml/config-file: added to search path
/usr/lib64/ocaml/config-file/config_file.cmo: loaded
Cannot find file /usr/lib64/ocaml/config-file/config_file.cmo.

Expected results:
Successful compilation / loading in toplevel, running the compiled program should print:
(* a field of type int *)
intfield = 0

Additional info:

Policy says [1] that ".cmo files are not normally included", but I think in this case it'd fall under the "if file is needed for link" exception, because the META file uses the .cmo and there is NO .cma built:

version="1.2"
description="a library to manage the configuration file(s) of an application"
archive(byte)="config_file.cmo"
archive(native)="config_file.cmx"
archive(plugin,byte)="config_file.cmo"
archive(plugin,native)="config_file.cmxs"

Alternatively upstream package could be patched to build a .cma
