This took a while to find. When the pullup of 
sys/arch/i386/stand/lib/Makefile.inc happened it didn't get pulled up
correctly. It's got a line wrong in it.

When you unset a var in shell if the var wasn't defined it sets $? to 1. This
will cause make to error out (and make it really hard to find....I need to
come up with a test case and send-pr against make on this). The main trunk has
the correct code and this simply adds back in the null'ing out the value, then
unset logic.

Here's the diff to fix: (I'm also typing up a send-pr right now)
