To help ensure that the GKI kernel and device kernel are kept in sync, test whether abi_gki_aarch64.xml matches between the GKI kernel and msm-5.10. This check is not fail-safe however. If an ABI impacting change is committed to either msm-5.10 or GKI tree without the corresponding ABI update, then this check will incorrectly proceed. The correct way is to do a full ABI comparison between msm-5.10 and the GKI tree with every build, however that is time-intensive. Thus, prefer to do the simple check for now.
