I guess it might have been broken by my patch to add support for
NetBSD-current, but I don't understand how. I'll attach the patch for
review - you can try removing it locally to confirm the theory.
The missing system was moved to its own file on -current, so we need
to include the new header now to get it.
I don't understand why including sys/param.h breaks the old way of
making the symbol available.

Fix build on NetBSD-current, where some symbols moved to a new header.
