[dpdk-dev] [PATCH v10 4/4] performance-thread: Fix cross compilation failed

[zhihongx . peng]

From: Zhihong Peng <zhihongx.p...@intel.com>

The gcc(arm-linux-gcc) will check code more stricter when ASan enabled.
"strncpy specified bound XX equals destination size" error occurs here.

Fixes: 116819b9ed0d ("examples/performance-thread: add lthread subsystem")
