--- Comment #6 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- > It bisects to r15-8901-g7bec4570301c43 which I find very surprising. Double > checked with a build of r15-8900-g525d4a10302113 (which works) and > r15-8901-g7bec4570301c43 (which doesn't). This patch does change the way host tools are built though.
