[PATCH v2 0/6] relocatable SDK

[Laurentiu Palcu <laurentiu.palcu@intel.com>]

Changes in v2:
	- addressed Saul's comments: added Upstream-Status for patches, signed-off-by
	  and patches description;
	- addressed Philip's comment about default installation directory: now the
	  default installation directory is the same as SDKPATH variable;
	- added patch for eglibc-2.16;


Hi,

This patchset adds relocatable SDK functionality. Instead of a tarball, the
output of "bitbake meta-toolchain/meta-toolchain-sdk" will be a self extracting
archive.

The user will then execute the .sh script and give it the target
directory for SDK installation (default is /opt/poky). The installer will then
extract the embedded tarball to the user provided location and will set up the
SDK: change the paths in the environment script, change the dynamic loader path
in all binaries and, also, change the ls.so.cache path in the dynamic loader
itself, together with the SYSDIR paths/lengths.

With that, no more root privileges are needed in order to install the SDK.

Thanks,
Laurentiu
