    bfd: Fix build with -DDEBUG=2
    
    When building with -DDEBUG=2, bfd doesn't compile:
    
    In file included from bfd/elfcode.h:2051,
                     from bfd/elf32.c:23:
    bfd/elfcore.h: In function ‘_bfd_elf32_core_find_build_id’:
    bfd/elfcore.h:354:3: error: implicit declaration of function ‘elf_debug_file’; did you mean ‘elf_debug_section’? [-Wimplicit-function-declaration]
      354 |   elf_debug_file (&i_ehdr);
          |   ^~~~~~~~~~~~~~
          |   elf_debug_section
    
    This happens because a guard in elfcore.h doesn't match the others.
    
    This patch fixes this, allowing the build to complete.
    
    Tested on amd64-pc-solaris2.11.
