commit b47f438d98cd4b731d7f4431448dde973eae4739
Author: Felix Fietkau <nbd at nbd.name>
AuthorDate: Thu Jul 21 17:49:19 2016 +0200

    build: remove image prefix from kernel files in KDIR
    
    This allows the image builder to change EXTRA_IMAGE_NAME at a later
    point in time without breaking the build
