From: Thomas De Schampheleire <thomas.de_schampheleire@nokia.com>

When the kernel architecture is overridden via BR2_KERNEL_ARCH_OVERRIDE,
this has an impact on the required architecture for qemu-system.

The correct architecture for Qemu is currently determined based on ARCH, not
KERNEL_ARCH. For example, while KERNEL_ARCH is 'powerpc' for all PowerPC
variants, ARCH may be powerpc, powerpc64 or powerpc64le. And this translates
to ppc, ppc64 and ppc64le for Qemu.

This means that it is not generically possible to determine the Qemu
architecture based on KERNEL_ARCH alone.

For now, already handle the case of x86_64.
