It seems that with gcc >5.x and -O2/-O3 optimization breaks packet
grouping algorithm in l3fwd-thread application causing segfault.
When last packet pointer "lp" and "pnum->u64" buffer points the same
memory buffer, high optimization can cause unpredictable results.
It seems that assignment of precalculated group sizes may interfere
with initialization of new group size when lp points value inside
current group and didn't should be changed.
With gcc >5.x and optimization we cannot be sure which assignment will be
done first, so the group size can be counted incorrectly causing segfault.
This patch eliminates intersection of assignment of initial group size
(lp[0] = 1) and precalculated group sizes when gptbl[v].idx < 4.
The same patch was applied for original l3fwd (af1694d94).

The patch fixes an inverted return value in the
cond_destroy and cond_init APIs of the pthread shim
example.
These APIs are now demonstrated in the sample app by
having the mutexes and condition variables
explicitly destroyed before the appplication terminates.
