I'm picking this up again - here is a new version of the patch, which
should address the base/ports issue and other problems.  Here's what
it does:

    - Add WITH_DEBUG_FILES src.conf knob to control standalone debug file
      generation, instead of using standalone files whenever DEBUG_FLAGS is set.

    - Switch debug file extension from .symbols to .debug, for consistency with
      other users of this feature.

    - Store debug files under /usr/lib/debug for base system components, and in
      a .debug subdirectory for other share/mk consumers.

    - Switch gdb to use the default standalone debug directory of
/usr/lib/debug.
