      Description

        On Linux aarch64, a JVM may encounter with three different page sizes: 4K, 64K and (when run on Mac M1 hardware) 16K.

        Since forgetting to specify --enable-compatible-cds-alignment is a common error, one which is only noticed when running the produced JVM on hardware with different page size, it makes sense to enable that option by default on Linux aarch64.
