Actually, I was slightly confused -- it is not a binutils bug.
The problem is entirely due to the presense of linkonce sections.

There are three copies of _ZNSs9_M_mutateEjjj in the objects
going into libstdc++.so.  Only one of these contains the PIC
thunk at the beginning of the section.  The linker chose a
version that didn't have it.

That is our bug.
