zArch_64 is not relevant/not used in the OpenJDK port to IBM System z. As noted elsewhere in the PR, it's the architecture name that was used in the initial, proprietary port by SAP. I found just one occurrence of the string in the head revision, and that was in test/lib/jdk/test/lib/Platform.java.
