Add the --as-needed linker flag to the DPDK library list in the pkg-config file so as to prevent overlinking. Without this flag, when linking statically using flags from $(pkg-config --static --libs libdpdk), all DPDK drivers and libs were statically linked in, but the binary was also requiring all the shared versions be present to run.
The real root-cause of this issue is that the DPDK libraries need to be duplicated in the linker command when doing static linking, due to the behaviour of pkg-config, but since that behaviour cannot be easily changed, this is a simple workaround to avoid problems.
