[dpdk-dev] [PATCH 7/8] mk: update LDLIBS for app building

[Sergio Gonzalez Monroy <sergio.gonzalez.monroy@intel.com>]

This patch does:
 - Update the app building command to link against librte_core.
 - Set --start-group/--end-group and --whole-archive/--no-whole-archive
   flags only when linking against static DPDK libs.
 - Set --as-needed when linking against shared DPDK libs.
 - Link against EXECENV_LIBS always with --as-needed flag.
