--- Comment #1 from Richard Biener <rguenth at gcc dot gnu.org> ---
I think that's known and was fixed upstream, but the easiest option is to pass
-fno-lto to stage2+ mpfr configure via the host_module config (need to figure
what environment to set exactly and/or invent extra vars honored by bootstrap)
We carry locally in our package
