[dpdk-dev] [PATCH 00/10] Add an option to use LTO for DPDK build

[Andrzej Ostruszka]

This patch series adds an option to make use of link time optimization
(if compiler has support for it).  It is split as follows:
- 1st patch (build) is the enablement
- remaining patches are fixes for the warnings produced by the compiler
  and they are split by directory/subsystem so their maintainers can
  easily find and verify the changes - please note that there are two
  groups:
  * errors (or possible errors) - with title "fix possible use ..."
  * false positives - warnings that _I_ think are not valid and the
    changes are made only to silence the compiler.
