Use the new oe-check-sstate to filter the sstate artifacts shipped with the extensible SDK by effectively running bitbake within the produced eSDK and and getting it to tell us which tasks it will restore from sstate. This has several benefits: 1) We drop the *-initial artifacts from the minimal + toolchain eSDK. This still leaves us with a reasonably large SDK for this configuration, however it does pave the way for future reductions since we are actually filtering by what will be expected to be there on install rather than hoping that whatever cuts we make will match. 2) We verify bitbake's basic operation within the eSDK, i.e. that we haven't messed up the configuration 3) We verify that the sstate artifacts we expect to be present are present (at least in the sstate cache for the build producing the eSDK). Outside deletion of sstate artifacts has been a problem up to now, and this should at least catch that earlier i.e. during the build rather than when someone tries to install the eSDK. This does add a couple of minutes to the do_populate_sdk_ext time, but it seems like the most appropriate way to handle this. Should mostly address [YOCTO #9083] and [YOCTO #9626].

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 = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website:

Where to Send Patches
=====================
As Poky is an integration repository (built using a tool called combo-layer),
patches against the various components should be sent to their respective
upstreams:
bitbake:
Git repository: http://git.openembedded.org/bitbake/
Mailing list: bitbake-devel@lists.openembedded.org
documentation:
Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
Mailing list: yocto@yoctoproject.org
meta-poky, meta-yocto-bsp:
Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp)
Mailing list: poky@yoctoproject.org
Everything else should be sent to the OpenEmbedded Core mailing list. If in
doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix of
oe-core and poky-specific files.
