Another reason is that when I configure CONFIG_CMD_ELF I will get lots of
warning such as:
cmd_elf.c: In function 'load_elf_image_phdr':
cmd_elf.c:289:15: warning: cast to pointer from integer of different size
[-Wint-to-pointer-cast]
cmd_elf.c: In function 'load_elf_image_shdr':
cmd_elf.c:343:12: warning: cast to pointer from integer of different size
[-Wint-to-pointer-cast]
cmd_elf.c:346:12: warning: cast to pointer from integer of different size
