Samuel, All,

On 2015-01-16 18:58 +0100, Samuel Martin spake thusly:
> When x86-64-efi platform is selected, grub2 automatically adds -m64 to the
> CFLAGS. This makes the configure script failed when the toolchain does not
> have multilib support (like the Buildroot ones).

I fail to see a case where we would want to build a 64-bit EFI GRUB to
later start a 32-bit kernel and userland.

Since we do not support multilib, the user would have to have two
builds: one for the 32-bit kernel+userland, one for the 64-bit
bootloader (if that is even possible to boot a 32-bit kernel from a
64-bit EFI GRUB).

Acked-by: "Yann E. MORIN" <yann.morin.1998@free.fr>

Regards,
Yann E. MORIN.
