---------------------------------
Because we has already add libc++ as compile flag. So I think maybe have some
other reason.

> Per [~StephanErb] and [~kevints]'s observations on MESOS-2940, stout's UUID
> abstraction is re-seeding the random generator during each call to
> {{UUID::random()}}, which is really expensive.
> This is confirmed in the perf graph from MESOS-2940.
