It works exactly the same way as on x86 platform

Tested that it works in https://github.com/malfet/deleteme/blob/hauptzweig/build_aarch64_wheel.py plan to use it for PyTorch aarch64 CI build

it would be nice to test it in the github ci too (at least build it)

@sylvestre updated and checked that scache-dist build succeeds on aarch64-linux : https://github.com/malfet/sccache/actions/runs/24673954202/job/72152435740?pr=1

### [`v0.16.0`](https://github.com/mozilla/sccache/releases/tag/v0.16.0)

[Compare Source](mozilla/sccache@v0.15.0...v0.16.0)

##### sccache 0.16.0

##### Summary

sccache 0.16.0 is a smaller, stabilizing release on top of 0.15.0's multi-tier caching work, with a few new capabilities:

- **Read-only backends**: Any storage backend can now be marked read-only, not just a select few ([#&#8203;2705](mozilla/sccache#2705)).
- **Remote execution on aarch64**: Distributed/remote execution now works on Linux aarch64, including fixes for `ldd` output parsing and toolchain packaging on non-x86\_64 Linux ([#&#8203;2668](mozilla/sccache#2668)).
- **CUDA**: `nvcc`'s `--dependency-output` argument is now handled ([#&#8203;2708](mozilla/sccache#2708)).
- **Resilience**: Fall back to a direct cache write when tempfile creation on the same filesystem fails ([#&#8203;2369](mozilla/sccache#2369)), and give a meaningful error when a multi-level chain references a backend that wasn't compiled in ([#&#8203;2695](mozilla/sccache#2695)).
- **Client efficiency**: The client and dist-client now use a single-threaded tokio runtime, avoiding a thread explosion when many short-lived clients run on many-core hosts ([#&#8203;2704](mozilla/sccache#2704)).
- **Correctness**: Strip `SCCACHE_BASEDIRS` from escaped-backslash paths on Windows ([#&#8203;2736](mozilla/sccache#2736)), ignore empty-set environment values in config ([#&#8203;2639](mozilla/sccache#2639)), and avoid the sccache wrapper when resolving the real compiler ([#&#8203;2720](mozilla/sccache#2720)).
- **Security/logging**: JWT keys and cert digests are now base64-encoded in logs ([#&#8203;2712](mozilla/sccache#2712)), plus general logging improvements ([#&#8203;2734](mozilla/sccache#2734)).
