Just for the record:

Until we are able to remove inter-CU order dependencies in our code, we are
sticking with:

  # prevent GCC from generating init_array:
  gcc-4.7/configure --disable-initfini-array ...

  # make gold use .ctors (we configure gcc to use gold)
  gcc-4.7 main.o ... -Wl,--no-ctors-in-init-array

I believe this fully restores the "legacy" (gcc-4.6) ordering.
