Subject: OCaml packages not building (due to updated python-pyyaml)

Hi Guix,

With commit ac02d423d3fcb11048ee2e4a02626fca40cf1419, which 
updated python-pyyaml to 5.4.1 (from 5.3.1) lot of OCaml packages 
fail to build.

This seems to be due to ocaml-dose3 that has python2-pyyaml as 
dependency for tests. ocaml-dose3 is a dependency of opam - a 
dependency of many OCaml packages.

The output when trying to build ocaml-dose3:

----------------------------------------------------------

----------------------------------------------------------

This seems to also be what CI is encoutering: 
https://ci.guix.gnu.org/build/623375/details

Any ideas? Any other packages failing for the same reason?

Would disabling tests for ocaml-dose3 be an acceptable quick hack?

Cheers,
pukkamustard
