No. That makes warnings almost impossible to notice. It's easy enough
to add V=1 (it's THREE characters) on those rare occasions where the
command is interesting. You can set it in your own environment if you
want.

Apparently OpenBSD shared libraries aren't linked with libc. That's a
quirk I haven't noticed before.
The simplest solution here is probably to just drop the -z defs option.
It doesn't actually do anything useful if everything is as it should.
What it does is prevent the link succeeding if something is accidentally
left unresolved. This can be useful when working on something, but it's
not really worth the effort of trying to figure out when it's safe to use.
