--- Comment #1 from Jim Wilson <wilson at gcc dot gnu.org> ---
This is actually a linker bug, not a gcc bug, and probably should be refiled in
the binutils bugzilla.
The symbol is in the tdata section of libstdc++. The RISC-V linker is creating
copy relocs from tdata to tdata.dyn in the output file. When marking sections
to keep, tdata gets marked as a kept section, but tdata.dyn is apparently not
being marked as needed, gets deleted, and the link fails. This appears to be a
RISC-V specific feature, so I will need to spend some time to figure out how to
handle this.
