For this second solution, what happens if some bozo selects *only* uart-modem
but not uart-core? If there's a strict ordering (hw-flow requires core, modem
requires both hw-flow and core), it's essentially the same thing as the first
solution. If there's not a strict ordering (i.e you can select uart-modem
without uart-core), you need to come up with sane semantics.
