We need an exception for armhf to unconditionally use objcopy's binary copy
mode as there's apparently no EFI target for binutils on armhf. Instead, the
crt0 composes the PE/COFF header directly, see
https://github.com/ncroxon/gnu-efi/blob/master/gnuefi/crt0-efi-arm.S#L25-L149.
The same is true for riscv64
(https://github.com/ncroxon/gnu-efi/blob/master/gnuefi/crt0-efi-riscv64.S). So
for both, we need to unconditionally use objcopy in binary copy mode.
This has and still works on Debian bookworm/stable with gnu-efi 3.0.15. For
Debian trixie/testing and sid/unstable which are now on gnu-efi 3.0.18, we need
to adapt and explicitly handle these cases. I'll post a patch soon.
Kind regards,
Christian
P.S.: Note that gnu-efi has a new home on GitHub since 2024-03-22 according to
https://sourceforge.net/projects/gnu-efi/ which is why I linked to the new one
above as it supports line ranges to be linked to.
