--- Comment #21 from Tamar Christina <tnfchris at gcc dot gnu.org> --- Hmm, I see what you mean. Currently though CXX is unable to find the lto plugin. It's somewhat confusing that CC is set to target and CXX is host (but reading back on the ticket you pointed that out as well). So I guess the question is why does CXX not contain all options to find it's plugins and why does this work on Linux. Do you happen to know where CXX is set?
