[yocto] ARM Cross Compiler SDK Toolchain

[Sunil Mukundan]

I usually build using bitbake -c populate_ext_sdk core-image-minimal

This builds the SDK in tmp/deploy/sdk in the form of a shell script
(which is actually a tar file with a script wrapper as a preamble).
running the script installs the sdk (interactively). Hope this helps.

Thanks
