I'm open to patches for building /[s]bin as dynamic.  If you have time and
can coordinate with lukem@netbsd.org to build the patch, I would
appreciate it.

Making a separate pw resolver program probably is too drastic a change, so
I think it's better to focus for now on a patch to allow building the
entire /[s]bin or user-selected parts as dynamic.
