We don't autoreconf/libtoolize binutils as it has very strict requirements, so extend our patching of the stock libtool to include two fixes to RPATH behaviour, as part of the solution to ensure that native binaries don't have RPATHs pointing at the host system's /usr/lib. This generally doesn't cause a problem but it can cause some binaries (such as ar) to abort on startup: ./x86_64-pokysdk-linux-ar: relocation error: /usr/lib/libc.so.6: symbol _dl_starting_up, version GLIBC_PRIVATE not defined in file ld-linux.so.2 with link time reference The situation here is that ar is built and as it links to the host libc/loader has an RPATH for /usr/lib. If tmp is wiped and then binutils is installed from sstate relocation occurs and the loader changed to the sysroot, but there remains a RPATH for /usr/lib. This means that the sysroot loader is used with the host libc, which can be incompatible. By telling libtool that the host library paths are in the default search path, and ensuring that all default search paths are not added as RPATHs by libtool, the result is a binary that links to what it should be linking to and nothing else.

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.
