请说明您试图build的OpenJDK的具体版本。

顶楼的问题：
你的build环境里，你没做任何代码改动前OpenJDK能正常编译完不？
总感觉你的G++没装完整…
或者你动过任何Makefile、*.make文件么？

那个ZipFile的异常其实是很隐晦的告诉你，jar命令试图解压的文件不存在。
jar xfv /NOT-SET/re/jdk/1.7.0/promoted/latest/binaries/linux-amd64/lib/tools.jar
看这个路径就知道了。路径里有/NOT-SET/，说明build的环境的环境变量没设够。我通常是把ALT_BOOTDIR和ALT_JDK_IMPORT_PATH都设到一个已经存在的、版本兼容的JDK上。
