Fix doing preroll for postroll

                self._dist(utils.get_dist_dir())

            else:

                # Postroll builds

                for i in range(benchmark.preroll):

                for i in range(benchmark.postroll):

                    ns = self._run_build(lunch, benchmark_log_dir.joinpath(f"post_{i}"),

                                         benchmark.modules)

                    report.postroll_duration_ns.append(ns)
