In some cases we want to pull in DEPENDS and RDEPENDS of recrdeptask dependencies but we need a way to trigger or avoid this behaviour depending on context. The logical syntax to trigger such behaviour would be a self referencing recrdeptask: do_a[recrdeptask] = "do_a do_b" The dependency chains already recurse this kind of expression correctly, the missing piece is to avoid any circular reference errors. Since the dependencies have already been recursively resolved, simply removing any recrdeptask references is enough to break the circular references. This patch therefore removes any circular references using the set difference_update() operator. There will be metadata tweaks required to add any references needed to the extra taskname.

Poky
====
Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a
reference manual which can be found at:
http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "") and contains only emulated machine support.
