select blows, film at 11.  TRACING blindly selects STACKTRACE, with a bunch
of stuff in kernel/tracing/Kconfig doing select of TRACING.  Not just an alpha

FWIW, we probably ought to make scripts/kconfig/conf check if dependencies
are satisfied before writing .config out and scream bloody murder if they
are not.
