The patch below should apply to the rust-1.23.0-r1.ebuild to make it work on arm64.
Its doing all the right things an my Pi3 right now LLVM is at 16% and its only building the embedded llvm for the Pi.
Don't forget the USE=nativeonly if thats what you want.
The build locks up in my QEMU arm64 chroot but that's not new.
We need the updated cargo too. I'll do that once rust builds

The Pi got to 2G in swap and after 10 hours overnight, no progress.

Here's the patch for cargo to make it arm64 aware and kind to memory impoverished systems.

Google says that my rust is too old.
