I doubt that. When I start building world this morning, I deleted /usr/obj/*.
So it should be not as you presumed.

I just did a 

make -j12 kernel 

in /usr/src again and it failed at the very same position. Again, the source
tree has been recently updated, afterwards I started buidlworld on a
deleted/fresh /usr/obj.
