[dpdk-dev] [PATCH] mk: remove "u" modifier from "ar" command

[Bruce Richardson <bruce.richardson@intel.com>]

On Fedora 22, the "ar" binary operates by default in deterministic mode,
making the "u" parameter irrelevant, and leading to warning messages
getting printed in the build output like below.

  INSTALL-LIB librte_kvargs.a
ar: `u' modifier ignored since `D' is the default (see `U')

There are two options to remove these warnings:
* add in the "U" flag to make "ar" non-deterministic again
* remove the "u" flag to have all objects always updated

This patch takes the second approach.
