Doing it this way lets us still keep the "logical" organization to
tell which object is which, even though we may lose physical
distinction by throwing all objects in a single library archive.

Incidentally this would slightly reduce the patch noise and make the
result more merge friendly when other topics are in flight that
touch these (like adding a new file or two to REFTABLE_OBJS), but
with the movement of these lines in [1/3], that benefit is
diminished.
