macOS Big Sur aarch64
After installation and with config and target set to defaults, Lazarus produces x86_64 executables and not aarch64 executables.
If I change the target CPU from Default to aarch64, the expected aarch64 executable is produced. However, starting a new project and it reverts back to x86_64.
[Update: The issue appears to be that Lazarus is not a Universal app like the FPC binaries, but just the x86_64 version, so it defaults to producing x86_64 executables]
