Bug#895994: ocaml-nox: Stop recommending deprecated camlp4

[Ralf Jung <post@ralfj.de>]

Package: ocaml-nox
Version: 4.05.0-10
Severity: normal

Dear Maintainer,

I just realized that ocaml-nox is the reason I still have camlp4 installed on my
system even though I have no intentions of using it.  In fact, the upstream
website at https://github.com/ocaml/camlp4 says:

> Since 2017, Camlp4 is not actively maintained anymore, and only receives
> occasional fixes for compatibility with new OCaml versions. Maintainers of
> Camlp4-using projects are actively encouraged to switch to other systems.

Sounds like it is time to drop the Recommends: camlp4 from ocaml-nox?

Kind regards,
Ralf
