I was surprised too. It seems some required configure/JDK changes got
integrated into 8u already.

I successfully built the entire thing with this as a bootstrap JDK on native AArch64:

checking openjdk-build os-cpu... linux-aarch64
checking openjdk-target os-cpu... linux-aarch64
...
checking for Boot JDK... /home/andrew/build/jdk8.zero
checking Boot JDK version... openjdk version "1.8.0-internal" OpenJDK Runtime Environment (build 1.8.0-internal-andre_2020_08_28_18_22-b00) OpenJDK 64-Bit Zero VM (build 25.71-b00, interpreted mode)
