Can you still build 'allnoconfig' after this? It will default to big-endian now,
and I'm not sure if this works with an nds32le toolchain.

On other architectures, we pass -mlittle-endian/-mbig-endian to the
compiler to force it into whichever mode the kernel is configured for,
but you don't seem to do that (or your gcc can't do it maybe).
