BTW, this kind of situation happens often enough, so how about doing
the following: teach kconfig that if FOO selects BAR and BAR depends
on <expr>, we should act as if FOO had explicit depends on <expr>.
Rationale: if FOO selects BAR, BAR depends on <expr> and <expr> is false,
turning FOO on will land us into unbuildable configuration (BAR turned on,
dependencies of BAR are not satisfied). It really happens often enough to
be very annoying. And we have fsckloads of dependencies that are there
only because of such scenarios. Gets especially nasty when BAR is selected
by several dozens of options and dependencies of BAR change...
Implementing that is pretty simply; the only thing I'm not sure how to deal
with is how to show such inherited dependencies in menuconfig et.al.
