This patch also does: - Set --start-group/--end-group and --whole-archive/--no-whole-archive flags only when linking against static DPDK libs. - Set --as-needed for all libraries but eal, malloc, mempool and ring when linking against shared DPDK libs. - Link against EXECENV_LIBS always with --as-needed flag.
