From GitHub (https://github.com/mozilla/application-services/issues/4828)

Right now, the artifacts generated by taskcluster are all built for Intel Macs (note that the rust.targets there only have darwin)
If we would like our android release to be accessible by M1s, we should probably change our taskcluster configs a little. I'm not sure the full extent of what's needed, but at the minimum:
Most likely need to split the taskcluster job for desktop-macos into two, one for M1s and one for Intel (including modifying the desktop-macos script to handle M1s.
Include darwin-aarch64 in https://github.com/mozilla/application-services/blob/main/taskcluster/ci/module-build/kind.yml#L43
Add a rust add target aarch64-apple-darwin in https://github.com/mozilla/application-services/blob/main/taskcluster/scripts/toolchain/cross-compile-setup.sh#L33
Properly set the environment variables like is done in https://github.com/mozilla/application-services/blob/main/taskcluster/scripts/toolchain/cross-compile-setup.sh#L2-L11 (this will probably look something like:
export ORG_GRADLE_PROJECT_RUST_ANDROID_GRADLE_TARGET_AARCH64_APPLE_DARWIN_NSS_STATIC=1
There are most likely more changes that need to be done, but this is hitting the end of my familiarity with taskcluster
Check-in with the taskcluster team to make sure all is OK, but if we can get an M1 to run a release megazord artifact, then we should be good
