There are some issues with this patch currently.

At a basic level, it needs well crafted test cases. You can find out how to write them by looking at other Driver tests.

But at a deeper level, the change here will be an very significant and potentially very disruptive change. While libunwind is your motivation, it could well have a dramatic impact on the selected set of libraries for links. I'm very concerned to make this kind of change without a *lot* of careful testing, and a very clear rationale about why this is the right search order *for all libraries*, not just libunwind. Because this applies to all libraries. =]
