The use case is generating Python marshaling and unmarshalling functions
only, i.e. calling pidl --python without --client. ATM we unnecessarily
generate, build and link a heap of idl code that is unused.

Okay, I'll put this patch on hold for the moment. I obviously need to
learn more about pidl internals and use cases before proceeding with a
proper fix.
