That would be your build host's python. The kernel module is pulling it
in as a dependency for the target, so it needs to be part of the rootfs
packages.

Check that your have python in your dependencies/image install lists,
which bitbake -e <your image type> will dump ... among many other
things :)

Which image type are you building ? core-image-minimal ? Try adding this
to your local.conf: IMAGE_INSTALL_append = " python"

Cheers,
