libstdc++ 2.90.8 builds itself, and rebuilds libgcc, with -fhonor-std.

Therefore, whenever you are going to link something with libstdc++ 2.90.8,
  you need to add -fhonor-std to your compiler flags.

I think this is your problem.

If you want to know more about -fhonor-std, see
  http://gcc.gnu.org/fom_serv/cache/68.html . If you find that explanation
  unclear or incorrect, tell me and I will fix it.
