I can't reproduce this.

I tried both my local next-20121005-based dev branch and that exact
commit above. I tried both the crosstool-ng-based compiler I normally
use and Ubuntu 10.04's ARM compiler (possibly from a PPA). In both
cases, I ran git clean -f -d -x ; git reset --hard HEAD first, and then
build zImage, dtbs, and modules, and of course used your attached .config.
