The build script and toolchain repositories are able to be found here:
  https://github.com/andestech/build_script.git

Is arch support in upstream binutils and gcc?

Yes, it is but only supporting elf-toolchain now. We will do the
upstream for Linux-toolchain in the next step.

Is the Linux toolchain only required for building user space, or do
you also need it
for building kernels? It's often possible to build kernels with a bare
toolchain, and
that helps a lot for automated testing.

Yes, nds32 kernel is able to be built with elf-toolchain too.
