Description of problem:
As I have been working on making some ocaml packages, I have repeatedly run into errors like this one:

Error: No implementations provided for the following modules:
         Seq referenced from /usr/lib64/ocaml/re/re.cmxa(Re__Core)

I believe this means that ocaml-re-devel should Requires: ocaml-seq-devel.  More evidence: %{_libdir}/ocaml/re/META has:

requires = "seq"

and %{_libdir}/ocaml/re/core.mli contains explicit references to Seq.

Version-Release number of selected component (if applicable):
ocaml-re-1.9.0-7.fc32

How reproducible:
Always.

Steps to Reproduce:
1. Try to build a module that consumes ocaml-re.
2.
3.

Actual results:
The error shown above.

Expected results:
ocaml-re-devel should pull in all of its dependencies
