Set BB_SIGNATURE_EXCLUDE_FLAGS, which is used by the new varflag checksum code in BitBake. The list is intended to cut out most of the varflags that are generated internally, don't influence the output or are already included in the checksum in some way. If need be this list can be extended in the future. The existing vardepsexclude mechanism can also be used to exclude undesired varflags, but they must be fully specified, e.g.: do_patch[vardepsexclude] += "do_patch[someflag]" Implements [YOCTO #2517].

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.
