Hm.  This seems like ... not the best way.  The problem is that
the preferred address could be very different based on the program
that uses the lib, not the lib itself.

...but, ignoring that part... :-)

I'm not particularly keen on the idea of using the "paddr" in the first
phdr to indicate the preferred address -- seems like it would be better
to insert a new entry into .dynamic which contained the necessary info.
