[PATCH] x86: efi: fix objcopy flags for barebox.efi

[corentin.guillevic]

From: Corentin Guillevic <corentin.guillevic@smile.fr>

Since the 2.46 version of binutils, a stricter target checking has been added
(see [1]) meaning that the --target=efi-app-x86_64 option no longer works:
a 'file format not recognized' error occurs.

Replace the --target option, which defines both the input and output targets,
with --output-target.

Hi Sascha,

can this patch please be added to the 2026.04 stable series? Missing
this patch currently prevents a successful build of Barebox for the x86
platform in Yocto wrynose.

Regards,
Lucas
