If ${PN} is empty and its existence makes no sense I think its
acceptable to do:

RDEPENDS_${PN}-dev = ""
RRECOMMENDS_${PN}-dbg = "${PN}-dev (= ${DEBPV})"

in the recipe itself. linux-libc-headers.inc does this for example since
${PN} makes no sense there.

There really aren't that many packages like this although there may be
some that have been dealt with in Poky but not in OE.
