[yocto] puzzle: simple recipe gets image dependencies

> Possible that attr dependencies traverse down to kernel

So it's attr.. I wonder how it gets those dependencies

"attr.do_build" -> "linux-yocto.do_deploy"
"attr.do_build" -> "linux-yocto.do_package_write_ipk"

Recipe .inc summary says "Utilities for manipulating filesystem
extended attributes"
And no visible deps on kernel..
