I don't think we need the compatible cds alignment here. This was added for x64 mainly to make it run correctly in rosetta IIRC. Macos aarch64 binaries will most likely run well in their native environment without this.

To answer Magnus, on line 1133, we define a different dependency, called "lldb". That dependency is an older devkit which only purpose is to provide lldb for the failure handler when running tests. We need this because we are still running tests on Macos < 10.15, but the new devkit requires 10.15.
