Well, that doesn't rule out memory trouble, but it's not very definitive 
for anything else. :-(

Have you tried deleting everything under /usr/obj and trying again?  
Worth a shot but if nothing comes of it and no better suggestions 
arrive, test that memory!

rm -fr /usr/obj/*
whatever make buildworld and buildkernel stuff you did.
