David got it building in the end, and I've rebuilt all of the OCaml packages in Rawhide (again ... and on the same day that OCaml 3.10.2 was released as well ...) They all build without error on ppc64 but that doesn't necessarily mean they will run. Just building them exercises the bytecode interpreter (written in C) and if we're lucky ocamlc.opt and ocamlopt.opt and on a rare few packages some tests. If someone can lay their hands on a ppc64 machine they can try them out. On the other hand it was a good enough excuse to finally get rid of 'ExcludeArch: ppc64' everywhere.
