treewide: add support for "lto" in PKG_BUILD_FLAGS
This reduces open coding and allows to easily add a knob to enable it treewide, where chosen packages can still opt-out via "no-lto". Some packages used LTO, but not the linker plugin. This unifies 'em all to attempt to produce better code. Quoting man gcc(1): "This improves the quality of optimization by exposing more code to the link-time optimizer." Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed that every buildsystem uses +$(MAKE) correctly. Signed-off-by: Andre Heider <a.heider@gmail.com>
