Not exactly sure what changed in ocaml 5.0 with regards to this, but when building a package that depends on `ocaml-ctypes`, the compiler now complains:

Running[1]: (cd src/c && /sbin/ocaml -I +compiler-libs /tmp/trizen-skaro/ocaml-luv/src/luv-0.5.12/_build/.dune/default/src/c/dune.ml)
Actual targets:
- recursive alias @install
File "/usr/lib/ocaml/ctypes/META", line 1, characters 0-0:

As `bytes` is a part of the compiler since 4.02, not requiring it explicitly should be fine and sure enough, when I apply this patch, everything seems to work:

archive(byte, plugin) = "ctypes.cma"

I've also applied the same fix (https://github.com/OCamlPro/ocplib-endian/pull/26) to the `ocaml-ocplib-endian` AUR package, which had the same issue, no problems there as well.
This task depends upon
