[oe] RDEPENDS_${PN} overwrites RDEPENDS_foo - bug or feature?

[Stanislav Brabec]

While verifying all aspects of proposed udev change, I experienced a
strange behavior of an udev recipe with RDEPENDS_udev:

RDEPENDS_udev is always ignored. Searching in deep, I found that
RDEPENDS_${PN} defined in update-rc.d.bbclass overwrites RDEPENDS_udev.

Once RDEPENDS_${PN} is defined, RDEPENDS_udev has no effect.

Is it a bug or documented feature?
