Hi Tom

Very Sorry about the build failure.
I shall verify it before sending to you.

Our teammates are trying to fix this problem.
I will offer you a refine one ASAP.

Because I always verify NDS32 on board (AG101P or AE3XX).
I never verify it on NDS32 QEMU.
It seem still have some problems, maybe need some time to debug for work.

But the RISC-V QEMU is available noe.
Maybe I can give it to you for trying.
