These headers all use TARGET_SIGNAL_H as header guard symbol. Reuse of the same guard symbol in multiple headers is okay as long as they cannot be included together. Since we can avoid guard symbol reuse easily, do so: use guard symbol $target_TARGET_SIGNAL_H for linux-user/$target/target_signal.h.
