Yeah, when I started in 2012, we didn't exactly have arm64 hardware :)

(And sometimes these days I'm still on x86.)

--target=aarch64-linux-gnu or --target=arm-linux-gnueabihf "just
works" with the caveat that 32-bit defaults to the U-Boot API version,
so needs --with-platform=efi for building the UEFI (including U-Boot)
flavour.

Several distros package cross compilation toolchains for both above
targets. Otherwise, latest (gcc 8) can be found at
https://developer.arm.com/open-source/gnu-toolchain/gnu-a/downloads
and less bleeding edge ones can be found under
https://releases.linaro.org/components/toolchain/binaries/

My smoke test is building an image with grub-mkstandalone and loading
a distro kernel/initrd in qemu with EDK2 images from
https://releases.linaro.org/reference-platform/enterprise/firmware/18.02/release/

qemu-system-arm -M virt -cpu cortex-a15 -m 1024M -bios QEMU_EFI.fd -hda 
fat:rw:fatdir/ -nographic -net none
qemu-system-aarch64 -M virt -cpu cortex-a57 -m 1024M -bios QEMU_EFI.fd -hda 
fat:rw:fatdir/ -nographic -net none

(I do that even when building/testing natively.)
