Perhaps. I didn't know sandbox was supposed to be buildable for other
arches than x86ish. I just tried doing the naive thing,

$ export ARCH=powerpc
$ export CROSS_COMPILE=powerpc-linux-gnu-
$ make sandbox_defconfig
$ make -j8
include/config_distro_bootcmd.h:335:3: error: #error "sandbox EFI
support is only supported on ARM and x86"

After trimming the .config to git rid of that, I get a million other
warnings and errors, so that doesn't seem to be the right way.

Can we please apply the patch to unbreak actual boards even if there's
no regression test for it?
