It is always a headache dealing with different defconfigs
though they only differ in a few places. Hence we are proposing a new
way of writing the defconfig:
1. Define a basic defconfig say mpc85xx_basic_defconfig
2. Spin off as much features as possible from the current mpc85xx_defconfig
	and create a separate config file, say, smp.config, kvm_500.config
Every time we add a new feature, we don't need to change several
defconfigs, we just add a new *.config
And you could merge any fragments you want into .config with the
current kconfig in Kernel.

Say you want to build mpc85xx_smp_defconfig, you do 4 steps:
make mpc85xx_basic_defconfig
make 32bit.config
make smp.config
make kvm_e500.config

With the new rules added into arch/powerpc/Makefile,
you can do it in one step:
make mpc85xx_smp_defconfig

The reason why I add new rules in arch/powerpc/Makefile is
because I don't want to break the build for existing defconfigs.

v2 changes:
 rename kvm_guest.config to kvm_e500.config
 utilize the definition of mergeconfig in scripts/kconfig/Makefile
 .config before and after this patch differs, need to investigate more
 need suggestions on what other features to spin off mpc85xx corenet32/64
