Following dpdk commits [1]-[3], it is now possible to compile with
--enable-Werror. Change the default to on, with an option to disable
using --disable-Werror.
Notes:
1. To compile against 21.11-rc1, need to apply [4] and [5] patches.
2. There are still sparse errors, due to dpdk issue. [6] fixes it.
