Thank you for your comment.
 
We prefer add toolchain/toolchain-external/toolchain-external-andes-nds32....

So we will submit these items in the next patch(v5).

1.add toolchain/toolchain-external/toolchain-external-andes-nds32
							+-- Config.in
							+-- Config.in.options
							+-- toolchain-external-andes-nds32.hash
							+-- toolchain-external-andes-nds32.mk
2.add support/config-fragments/autobuild
				+--toolchain-configs.csv
				+--andes-nds32.config
