[kernel] Move the 'prep all configs' to a separate script.

commit 384fed008db95925ccee2c0c632dbc4e6133f40c

    Move the 'prep all configs' to a separate script.
    
    This cuts make prep time down from 53s to 10s on my desktop.
    A full run across all archs can be done from within a source
    tree by running ../../scripts/allarchconfig.sh
