aarch64 rust install failure

[Ron Georgia <netverbs%gmail.com@localhost>]

I have a Pinebook 1080P. I tried to build firefox on it and after three days of building I got the error listed below. I tried to install rustup but got an error; no evbarm. I added evbarm to the rust-init.sh switch statement. Another error I keep running into is libstdc++.so.8 not found.

evbarm)
            _cputype=aarch64
            ;;

Now when I run it I get this error:

$ ./rustup-init.sh
info: downloading installer
curl: (22) The requested URL returned error: 404 Not Found
rustup: command failed: downloader https://static.rust-lang.org/rustup/dist/aarch64-unknown-netbsd/rustup-init /tmp/mktemp.eaADP6ji/rustup-init
