Oddly, his 6.4.0 gets farther along than his 7.3.0 ones, but still
doesn't work as I get things like this:
AS arch/nds32/cpu/n1213/start.o
arch/nds32/cpu/n1213/start.S: Assembler messages:
arch/nds32/cpu/n1213/start.S:256:
Error: Incorrect syntax, sethi $ta,hi20(_start@GOTOFF).

arch/nds32/cpu/n1213/start.S:256:

and it just keeps going from there. You may want to drop him an email
about how he's configuring for nds32le. Last time I talked with him, he
wasn't planning to re-spin the 7.3.x ones, but he might do gcc-8 once
it's ready.
