--- Comment #2 from Andre Heider <a.heider at gmail dot com> --- Additionally, LDFLAGS_FOR_TARGET isn't part of the configure help: ./configure --help|grep FOR_TARGET LD_FOR_TARGET is, attempting to shove LTO in there yields other problems (or I am be doing it wrong). I only found LDFLAGS_FOR_TARGET via grep. If that isn't by intention it would be nice to add it there too.
