I quote the README from gnu-efi:

.......... quote begin ............

- A version of "objcopy" that supports EFI applications.  To
      check if your version includes EFI support, issue the
      command:

        objcopy --help

      Verify that the line "supported targets" contains the string
      "efi-app-ia32" and "efi-app-x86_64" and that the "-j" option
      accepts wildcards.

............ quote end ............

That's why I assume that it's not supporting it.


Kind regards
