Since it comes from ld (or collect2?) and that's an LTO link, I suppose it
might be a race condition. I agree, it should be a separate bug. Maybe add
Michael Matz for binutils and Martin Liska for GCC LTO. IBM tends to have
weaker memory models, and that race might just not materialize with the
stronger model of x86.
