This patch fixes up the issues that were being seen where BBCLASSEXTEND and PACKAGECONFIG were interacting badly. It also ensures PACKAGECONFIG interacts properly with multilib builds. Ideally some of this code will be abstracted into lib/oe/classextend.py but at this point in release more invasive changes like this are inappropriate. This patch also removed empty strings from expressions rather than passing them around as this was complicating the additional code unnecessarily. The patch was verified against the OE-Core metadata where the return values of expandFilter() were sanity checked by hand for native/nativesdk and multilib combinations.

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/community/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.
