Hum.. I assumed that WITHOUT_ASSERT_DEBUG was a rare case and used as
part of producing a production release where one knows /usr/src builds
as-usual.  -Wno-unused would scratch this itch, but we need to find a way
to codify it so that we're not putting GCC options into share/mk.  I
guess make a NO_WUNUSED knob.
