To fully support dpdk extensions (loading of .so), all symbols provided by dpdk libraries must be available in the binaries: before this patch, unused functions/variables from dpdk static libraries could be stripped by the linker because they are not used. These symbols can be used by a dpdk extension that is loaded at runtime with the -d option.
Adding --whole-archive when generating a binary solves this issue.
