Building x86_64:tools/perf ... failed
--------------
Error log:
  PERF_VERSION = 4.4.176.gbd5033
  builtin-trace.c: In function ‘perf_evlist__add_vfs_getname’:
  builtin-trace.c:2414:2: error: implicit declaration of function ‘evlist__for_each_entry_safe’; did you mean ‘hlist_for_each_entry_safe’? 

builtin-trace.c:2414:2: error: nested extern declaration of

  bool found = false;
       ^~~~~
builtin-trace.c:2430:1: error: control reaches end of non-void function
