    binutils234: Patch readelf(1) to recognize DragonFly-specific notes
    
    * Define NT_DRAGONFLY_ABI and NT_DRAGONFLY_NOINIT in
      'include/elf/common.h' according to 'lib/csu/common/notes.h'.
    * Add process_dragonfly_elf_note() to readelf.c to decode
      DragonFly-specific notes.
    
    Before:
    ```
    % readelf -n /bin/sh
    
    Displaying notes found in: .note.tag
      Owner                Data size        Description
      DragonFly            0x00000004       NT_VERSION (version)
       description data: c8 29 09 00

       description data: 00 00 00 00
    ```
    
    After:
    ```
    % readelf -n /bin/sh
    
    Displaying notes found in: .note.tag
      Owner                Data size        Description

      DragonFly            0x00000004       NOINIT (C runtime no init)
    ```
