Yes, this is hypothetically possible, see:

So, ocaml.i386 would resolve this dependency just as well as
ocaml.x86_64, but I doubt it would work. yum is going to try to resolve
this dependency with the ocaml.x86_64 by default, but if you had somehow
manually installed ocaml.i386 only, it would then install ocaml addons
as x86_64 packages.
