So I'm working on a script that autocompiles from the source code without asking the Maidsafe team if they would pretty please release an aarch64 binaries of their sn_cli, auth and node

I’m a little out of the loop on what you’re trying to achieve, but I don’t think you need the host to have the same architecture. The cargo GitHub Action supports flags that enable cross-compiling using cross. Perhaps that’s something to look at? I’ve compiled Safe successfully in the past for aarch64 for the Raspberry Pi using cross.
