Subject: [PATCH 10/63] perf beauty: Wire up the renameat flags table generator to the Makefile

From: Arnaldo Carvalho de Melo <acme@...hat.com>

Now when we run 'make -C tools/perf O=/tmp/build/perf' we end up with:

  $ cat /tmp/build/perf/trace/beauty/generated/rename_flags_array.c
  static const char *rename_flags[] = {
	[0 + 1] = "NOREPLACE",
	[1 + 1] = "EXCHANGE",
	[2 + 1] = "WHITEOUT",
  };
  $
