--- Comment #5 from Hans-Peter Nilsson <hp at gcc dot gnu.org> ---
JFTR: I have a feeling there's a (non-build-machinery) target-specific bug here
too, one that trigs a binutils bug.  In any case, I have to build gcc for
myself to avoid a back-and-forth game of requests to include sufficient archive
and object files in the report (like I should have done regularly anyway, mea
culpa).
