run-via-rtld-prefix checks whether the program to be run is a static test and skips if it is. This is fine, except that it assumes that the program to be run is the second $^, which is true only for tests. This change creates an rtld-prefix, which is simply the dynamic linker prefix with the necessary arguments and uses that in the non-test targets.
