error: building kvm for powerpc using cross compiler on x86

[Dushyant Bansal]

I want to build kvm kernel module for powerpc using cross compiler. I 
downloaded kernel source code from 
http://www.linux-kvm.org/page/PowerPC_440_Host_Kernel. Inside that 
kvm_source folder when I do "make ARCH=powerpc menuconfig", inside 
virtualization menu, option "kvm" is not present. I have attached the 
screenshot.

Thanks,
