It looks like the problem had to do with the Architecture settings on my sub projects. Xcode 4.2 changes the default Architecture to just armv7 instead of both armv6 and armv7. I had updated my main project to armv6 and armv7, but the sub-projects were still only using armv7. Once I updated all of the sub-projects then it started linking properly.
