On a relate topic.

Last time, tried build a DPDK application using -fwhole-program gcc gave
lots of warnings because it decided not to inline rte_memcpy.

Perhaps this might impact LTO as well. Really rte_memcpy_func should not
be inline. We already optimize for the constant size case where inline
makes sense. After that not so much.
