In order to enable basic multilib support for the export of an SDK image, a number of minor changes had to be made: The value of MULTIMACH_TARGET_SYS needs to be variable. This way we can define the value to the appropriate multilib. (Also in some cases the default PACKAGE_ARCH is set to MACHINE_ARCH which is incorrect for the SDK.) Add a companion REAL_MULTIMACH_TARGET_SYS, based on code from meta-environment, to allow for this. We have to convert the do_populate_sdk into a python call, and then break up the previous items into three parts. * Image construction * Setup of environment files * Generation of the tarball Then we can iterate over the multilibs to populate the environment files. Finally, matching changes were needed in the toolchain-scripts file. And what I presume is an optimization of immediate evaluation for TOOLCHAIN_CONFIGSITE_NOCACHE and ..._SYSROOTCACHE needed to be done at runtime, otherwise the wrong values may be used.

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.
