I think the intention is to set the initial value to blank, and ensure that
${PN} is the first item in the list (since _prepend gets applied later). If you
just simply had PROVIDES = "${PN}" then it could be overridden somewhere else
such that ${PN} was not in PROVIDES at all, which would be counter-intuitive.
