MaxOS X Spoon VM grief

Ok, I poked at this for a few minutes this afternoon.
The issue is that when building a debug VM under x-code it cheerfully
generates a zero-linked VM, meaning nothing is linked and routines are
This causes a crash because Craig's VM changes overlaid with the latest
VMMaker resulted in two missing routines in interp.c. Since you don't
get a link failure you
don't know there is an issue until run time.
Adding the two routines makes the build and run successful.
I'll note that you can turn zero-linking off, which perhaps is a wise
decision when building a new hacked VM/plugins since it then lets you
know right away if you
are missing any routines, versus later and perhaps in a situation
that's harder to debug.
