Am I missing something?
Hi, The latest upload from December builds fine on i386, amd64, armhf and arm64, and as far as I can see it's building the EFI binaries with the right LD scripts from gnu-efi, eg: elf_aarch64_efi.lds, elf_ia32_efi.lds So I think we can close this one too? -- Kind regards, Luca Boccassi
