Try to use commit dc3b0673ae5efb73edab66ec5c2f074272e9a4df.
But this command does not work (I remember it used to work):
# GCC_VERSION=9.3.0 make.cross ARCH=arm

I can hardly believe it can't work.
I get
# file include/linux/vringh.h
include/linux/vringh.h: C source, ASCII text
So this looks like a false positive to me?
