更改 configure 以使用 Python 的 sysconfig 模块代替已弃用的 distutils 模块来确定如何构建 PL/Python（Peter Eisentraut，Tom Lane，Andres Freund）
\n对于 Python 3.10，这避免了在 configure 时出现关于 distutils 已弃用并计划在 Python 3.12 中移除的警告。想必一旦 3.12 发布，configure --with-python 将会完全失败。这种面向未来的改进确实有一个代价：sysconfig 在 Python 2.7 之前不存在，在 Python 3 分支中在 3.2 之前也不存在，因此不再可能针对早已停止维护的 Python 版本构建 PL/Python。
