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.
