Same thing: misplaced Signed-off-by line.

Please keep those lines, but update them to use 3.15. Otherwise, the
default kernel headers version is used, which we regularly update. And
then, as soon as 3.16 is released, this defconfig is going to build a
3.15 kernel, with a toolchain that has used 3.16 kernel headers, which
is bad. So for all defconfigs, we want to lock down the kernel headers
version.

Thanks,

Thomas
