    bitbake: Show base multiconfig environment
    
    Adds support to the 'bitbake -e' command so that it can display the base
    environment for a multiconfig. It was previously possible to get the
    base environment for the main environment by running "bitbake -e", but
    there was no support for getting the base environment for a multiconfig
    without specifying a recipe. A user can now print the base environment
    for the multiconfig "foo" by running:
    
     $ bitbake -e multiconfig:foo
