Sorry for getting back to you so late.

    kbuild: fix cscope so it does not emit warnings
    
    This patch fixed the following errors when doing "make cscope" and
    "make cscope ARCH=um".
    
      FILELST cscope.files
    find: arch/i386: No such file or directory
      MAKE    cscope.out
    
      FILELST cscope.files
    find: include/asm-i386: No such file or directory
      MAKE    cscope.out
    
    In addition it teach kbuild to delete ncscope.out at mrproper
