Add a new option LTO that enables the new link-time optimization framework
and first optimizations that GCC 4.5 brings. This adds libelf as a new
dependency (if used) and is off by default; we may be enabling it at a
later point, though.
Bumping PORTREVISION since someone who has installed libelf, previously
to this change would get LTO enabled automatically and then run into
problems if libelf is removed -- which is possible, since this port
does not lay down a dependency on that case.
