What do you mean by "we even source raw Kconfig path"? It was not
sourced before this modification unless CMD_NAND was selected.

I agree we should also remove this link between a path being
compiled and a CMD_* symbol in the root Makefile. It will probably
produce a lot of errors though. I'll try when I'll have some time.
