--- Comment #11 from Eric Gallager <egallager at gcc dot gnu.org> --- Update: I finally managed to bootstrap using one of Simon Wright's releases: https://github.com/simonjwright/distributing-gcc/releases I still think there might be a bug in the build system somewhere leading to the wrong tools getting used, but since I've managed to build now, I'm not going to bother looking too much harder...
