There isn't necessarily a 1-to-1 mapping so this is tricky. For Keno's use
case cc1 is probably fine, but for more general build reconstruction /
tooling stuff the driver is preferable based on my experience.

We may not want to conflate the two use cases (since I suspect the CC1 case
is much more straightforward).
