    The real problem is when say CONFIG_FB are empty. Then kbuild will see:
    obj-$(CONFIG_PPC) which I doubt was what you wanted.

    This can be fixed by changing Kconfig to evaluate all known symbols to
    either y,m,n - in contradiction to today where symbols that evaluate
    to n is left empty.
