It's a matter of choice, I figured out how I am going to handle it (link in a profile but not in signature) and that works for me, your mileage may vary.
I get plenty of traffic that way as it is, and I'd rather have visitors who really want to know something about me than someone who idly clicks on a forum signature just because it's there.
If you have fewer than a hundred links, it's probably not a big deal. If you have a few thousand, then you might want to think about your strategy.
But if you haven't paid anyone to post your links in forums, and you don't have thousands and thousands of them showing up in GWT, then you're probably overthinking it. It's really easy to fixate on little bushes like this and overlook the trees or the forest.
