Nothing wrong with building your own version, but you'll want to disable profiling in most cases (the profiling code will noticeably hurt performance). The files in the gprof subdirectory are produced by the profiler.
The error message you see (Stale file handle) suggests that you are using an NFS-mounted filesystem and that someone may have deleted a directory while you were running the backup. That may be ok, but I personally would not trust a backup that reported an error (especially if you can't explain the error, which I can't).

I am guilty of compiling the code myself and enabling the profiling. I am new to Postgres and was following the previous DBAs work. I now realize this needs to be off and will look to be recompiling the code again. I am thinking I will create a new software home and point the database there.

Did you compile your copy of PostgreSQL 9.5 yourself, and if so, did you enable profiling? If not, which installer did you use?
-- Korry
I have just implemented pg_basebackup on my 9.5 PostgreSQL database. I received the following notification:
pg_basebackup: could not create file "<base_directory>/fullbckp_20160225/gprof/2540/gmon.out": Stale file handle
Is this an issue or can this be ignored since these are tracing files?
