Yes, it'd be very much nicer if Kconfig supported that sort of
dependency but without that the hack with selects does seem about as
good as it gets if you want to do it via Kconfig.  I rather suspect this
is why it's common to have an ifdef tree for these things rather than
trying to push them through Kconfig.
