I tested this using
https://developer.arm.com/-/media/Files/downloads/gnu-a/10.2-2020.11/binrel/gcc-arm-10.2-2020.11-x86_64-aarch64-none-linux-gnu.tar.xz
But I had to modify the cross compile prefix in
config/arm/arm64_n2_linux_gcc (adding a none_).
I am still interested in a toolchain that works out of the box.
Series applied, thanks.
