Gentoo defines ARCH == HOST_ARCH. Be careful that if they are
different, vboot-utils will try to use Qemu.

But it's quite weird to have a dependency on the target architecture
when building a host tool. Looking at the ARM specific code for
example, it pokes into /proc/firmware/device-tree/, which obviously has
no chance to exist on the build machine.
