This list is really for discussion about bitbake itself. One of the
Yocto lists would be more appropriate for this question.

The easiest way to do this is simply to add tar into your image.
IMAGE_INSTALL_append = " tar" in local.conf would probably do this for
you (the space before tar is important).
