[dpdk-dev] [PATCH v4 1/2] mk: allow duplicate linker flags in libraries list

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

Since [1] duplicates in LDLIBS are removed. The side effect is that it
does not distinguish between libraries or linker flags.

This patch allows multiple linker flags in LDLIBS, such as
--whole-archive.
