Bug#858626: libllvm-3.8-ocaml-dev: Package is empty

[Cyril Soldani]

Package: libllvm-3.8-ocaml-dev
Version: 1:3.8.1-18
Severity: grave
Justification: renders package unusable

Dear Maintainer,

The package `libllvm-3.8-ocaml-dev` does not ship any library. It only
contains the following files:

    /usr/share/doc/libllvm-3.8-ocaml-dev/NEWS.Debian.gz
    /usr/share/doc/libllvm-3.8-ocaml-dev/changelog.Debian.gz
    /usr/share/doc/libllvm-3.8-ocaml-dev/copyright
    /usr/share/lintian/overrides/libllvm-3.8-ocaml-dev
    /var/lib/ocaml/lintian/libllvm-3.8-ocaml-dev.info
    /var/lib/ocaml/md5sums/libllvm-3.8-ocaml-dev.md5sums

It misses the `/usr/lib/ocaml/llvm-3.8` folder, which should contain the
libraries, making the package totally unusable.

It looks like this folder is missing since `libllvm-3.6-ocaml-dev`, and
is still missing in `libllvm-3.9-ocaml-dev`. Last version containing it
was `libllvm-3.5-ocaml-dev`, but it is not installable on `stretch`.

The change log mentions that OCaml bindings were disabled in November
2014, because `libctypes-ocaml` 0.3.3 was needed, but not available.
Would it work with a current version of that library? (0.7.0 is
installed on my system)

Thanks in advance for your help.
