PATCH 2/3 toolchain: only external toolchain option displayed

Currently csky architecture isn't support the "internal toolchain backend", so we disable it in config.

PATCH 3/3 csky: Add new architecture

In reply to Guo Ren

This is a basic implement for C-SKY, we use pre-build-toolchain from url, and csky-toolchain open-source is on going.

Thanks again for your patch series, but you did not read carefully enough the comments in my previous review.

Your patch 1/3 is adding board configuration for an architecture for which the support is only added in patch 2/3. This doesn't make any
sense: I should be able to apply any number of the first patches in your series, and still get something that make sense.

So:

* Please merge patches 2/3 and 3/3 in just one patch, and make them the first patch.

* Please move your current patch 1/3 as the second patch of your series.

Thanks!

Thomas
