buildkernel broken after r326553

Hi,

Looks like one of the commits by Bryan (r326549-r326553) has broken the 
kernel build for me (using -j32, but serial build did fail as well) -- 
checking out r326547 make it work again.

I can't pinpoint the exact error in the build log, as it seems to be 
some make weirdness, so here's a guess, please let me know if you need 
full build log:
