    classes/populate_sdk_ext: allow including toolchain in eSDK on install
    
    If we're to completely replace the standard SDK with the extensible SDK,
    we need to be able to provide the standard toolchain on install without
    doing anything other than installing it, so that you can install the SDK
    and then point your IDE at it. This is particularly applicable to the
    minimal SDK which normally installs nothing by default.
    
    NOTE: enabling this option currently adds ~280MB to the size of the
    minimal eSDK installer. If we need to reduce this further we would have
    to look at adjusting the dependencies and/or the sstate_depvalid()
    function in sstate.bbclass which eliminates dependencies, or look at
    reducing the size of the artifacts themselves.
    
    Implements [YOCTO #9751].
