Is there a package with the aarch64 version of gcc-arm-none-eabi for bare metal Newlib?

On Ubuntu 18.04, I was able to use gcc-arm-none-eabi successfully with Newlib as described at: https://github.com/************2/gem5-bare-metal-examples/tree/994a4b5085bba62331704889b9689c7b261c289d

Now I wanted to try some aarch64 bare metal code as explained here. Is there an analogous package that supports Newlib?

If you can do it if crosstool-ng or from scratch, I'm also interested (here is my failed attempt), but ideally there should be a package to make things even easier.
