We can't use `dladdr()` in the tests, because when we're statically linking with musl that function is a no-op. Additionally, because musl disables emission of unwind information in its build, and because its signal trampolines don't include unwind information, tests that involve unwinding through a signal handler won't work and need to be disabled for musl. rdar://123436891
