[Buildroot] [git commit] bootlader/grub2: disable x86-64-efi choice on !BR2_ARCH_IS_64

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=fcc8d123ea18dfbe41800ffd84a864b9ce9ff10e
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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).
