--- Comment #23 from Richard Biener <rguenth at gcc dot gnu.org> --- The patch looks pretty obvious to me - though I wonder if archives still work on x86_64-linux after it (or rather I wonder how they worked before...). I'm not aware of @ doing any magic for filenames - do they? So - please test this with boostrap-lto on x86_64-linux as well.
