为什么警告会导致 openJDK-11 构建崩溃？

Question

我需要

git clone --depth 1 --branch jdk-11+28 https://github.com/openjdk/jdk.git

在 aarm64 NAME="Simply Linux", VERSION="9.1 (Destiny)" 上

构建以下 openJDK我运行：

    bash ./configure
    make images > make.log

它失败并出现以下错误 (make.log)

我做错了什么？ 在哪里可以提交有关 openjdk11 的错误报告，或者讨论这个问题？
