Bug#906596: grub2: secure boot source templates build same source on different architectures
The source template in grub-efi-amd64-signed-template _amd64.deb and
_i386.deb builds the same source package: grub-efi-amd64-signed.
That is not possible.
Same for the ia32 version.
I suggest to only build the signed version for the native architecture
(i.e. grub-efi-amd64-signed only on amd64). People should still be
able to install the other version via multi-arch if required (though I
guess most people will use amd64 and x86_64 EFI).
The binary package description in the source template is also wrong:
| Package: grub-efi-amd64-signed
| Architecture: i386
| Description: GRand Unified Bootloader, version 2 (i386 UEFI signed by Debian)
as it talks about `i386 UEFI` for grub-efi-amd64-signed.
