What I do:

Grab https://mirrors.edge.kernel.org/pub/tools/crosstool/files/bin/x86_64/13.2.0/x86_64-gcc-13.2.0-nolibc-aarch64-linux.tar.gz

untar that into /opt/crosstool

And my crufty old script does, partly,

	WHAT="$*"

	...
	[ $ARCH = arm64 ] &&    CT=gcc-13.2.0-nolibc && XARCH=aarch64-linux
	...

	PATH=$PATH:/opt/crosstool/$CT/$XARCH/bin export PATH
	export CROSS_COMPILE=/opt/crosstool/$CT/$XARCH/bin/$XARCH-
	export CC="/opt/crosstool/$CT/$XARCH/bin/$XARCH-gcc"
	J=$(grep "^processor" /proc/cpuinfo | wc -l)
	J=$(expr $J \* 2)
	nice -20 make -j$J CC="$CC" $WHAT 2>/tmp/log-$ARCH

setenv ARCH arm64
crufty-old-script vmlinux modules

Worked for me, thanks.
