Actually, you're right, rdmd is supposed to automatically link all
dependent files. I just tried your code in my environment (Linux 64-bit,
git HEAD) and I didn't see this problem. I wonder if it's a bug that has
since been fixed?

Maybe you can try inserting this line into sample_a.d:

	module sample_a;

I'm not sure if that will help, but just trying to narrow down the
problem a bit.
