Actually, having asked you to add this code, I am now wondering if it is needed after all.

Since the linker runs with `--gc-sections` enabled by default I think the presence of these unreferenced sections in the object file should be harmless.   However keeping the object files free of unused sections also makes some sense.  I'll let you decided if you want to keep this code.

lgtm either way.
