This requires significantly more time to implement for Zero. To unblock the
rest of the Lilliput work, I suggest we protect Zero with this hunk:
diff --git a/src/hotspot/cpu/zero/vm_version_zero.cpp
b/src/hotspot/cpu/zero/vm_version_zero.cpp

...and then deal with the rest in https://bugs.openjdk.org/browse/JDK-8307532.
