I vote for the first approach. It works in my testing
and it is what we will eventually need to do once we
start building rwtest as a shared library.

Btw., I note that the -Wl,-bsvr4,-R$(LIBDIR) option
is on the library link line. I don't see why we need
to specify it there. Unless you have a goof reason
for it to be there can you please remove it?
