Incorrect binaries in the images with kernel sources

[steev]

Due to the way the images are created and cross compiling the kernels, because we run
make modules_prepare after the kernel, some of the utilities are x86_64 binaries so they won't run on the devices.

Users need to make clean and then make modules_prepare in /usr/src/kernel
