Another try packaging janest-core etc. for Debian -- some help needed

[Hilko Bengen <bengen@debian.org>]

Hi,

in the last few days I have given packaging a recent version Jane
Street's standard library another try and the sources now seem to build
fine. Some more build dependencies have been introduced which I have
documented that in the BTS and prepared packages for. So I am more or
less ready to upload.

However, I cannot get the build system to generate API documentation.
When I run

    ocaml setup.ml -doc

nothing is generated and I can't figure out why. All the dependencies
have the same issue. Could somebody please have a look at why no API
docs are generated for i.e. sexplib310 so we can fix this for all the
janest-core dependencies? Thanks.

Cheers,
-Hilko
