Title:
  objcopy fails to recognize x86-64 libraries

Status in binutils package in Ubuntu:
  Invalid

Bug description:
  I am running amd64 Ubuntu 26.04 with binutils
  2.45.50.20251125-1ubuntu1

  When building upstream U-Boot
  (https://source.denx.de/u-boot/u-boot.git) with

  make sandbox_defconfig
  make V=1

  I get an error

    objcopy -j .header -j .text -j .sdata -j .data -j .dynamic -j .dynstr  -j .dynsym -j .rel* -j .reloc --target=efi-app-x86_64 lib/efi_loader/helloworld_efi.so lib/efi_loader/helloworld.efi
  objcopy: lib/efi_loader/helloworld_efi.so: file format not recognized

  $ file lib/efi_loader/helloworld_efi.so
  lib/efi_loader/helloworld_efi.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped

  When reverting to bintuils 2.45-7ubuntu1.1 the error disappears.
