Hi Nick,

Threads is a dummy dependency for Clang. For MinGW without pthread it still
adds -pthread switch (and it comes to libdpdk.pc), but executable doesn't
require pthread library to run. I can imagine DPDK built by MinGW without
pthread be linked via pkg-config to an app built by MinGW with pthread, then
-pthread switch will be added from libdpdk.pc. Do you think it's an issue?
