Richard Purdie 56e46f0bc4 bitbake/ast: Fix ??= vs. ?= handling
As the code stands, setting a variable with ??= could result in a ?=
variable not overriding it. This patch fixes the issue by allowing
the ast to make lookups that ignore any ??= set variables.

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

For information about OpenEmbedded see their website:
