You can enable plugins based on architecture by setting the 'architectures'
member of the plugin to a list of strings describing the allowed
architectures, e.g. ['x86_64', 'ppc.*'].

If you need more fine grained control within a plugin then you can use a
predicate to restrict specific file, command or other collection according
to platform:

  ppc_p = SoSPredicate(arch=['ppc.*'])
  self.add_cmd_output("ppc_only_command", pred=ppc_p)

And "ppc_only_command" will only execute if the runtime architecture matches.
