Make IDLE installation optional

Feature or enhancement

Proposal:

IDLE is useful at development-time, but a graphical IDE isn't something that needs to be present, for example, in a container image containing production code. IDLE is a standalone app with no dependents elsewhere in the standard library, so it's trivial to strip from the installation directory after running make install - by removing lib/python3.x/idlelib/ and the executable/symlink in bin - but it'd be much more convenient if it were possible to tell configure not to install it in the first place.

This could be implemented with a new option, --without-idle. This would allow IDLE to be installed by default for backwards compatibility, while permitting it not to be installed in situations where it isn't needed.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

首先跟踪 configure 选项的处理方式，以及将 IDLE 放置到 lib/python3.x/idlelib/、将其可执行文件或符号链接放置到 bin 中的 make install 规则。检查 gh-117684 的工作如何处理安装，并验证新选项会跳过这些文件，同时默认安装保持不变。
