Subject: mk: allow duplicate linker flags in libraries list
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=1ed3852fa9cd259ece5bbe257abe3c58b69b8fdb;p=dpdk.git

mk: allow duplicate linker flags in libraries list

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.
