    is there any strong reason why undefined symbols aren't equivalent to
    symbols with a value of "n"?

    Many !=n seems to be bogus (especially ones from the automatic
    transition to the new Kconfig) and I'll audit them. But rewriting valid
    FOO!=n to (FOO=y || FOO=m) doesn't sound like an improvement.
