Description

I've noticed that, starting with the 20250517 build, the file size of the python executable file is significantly larger than in builds from 20250409 and earlier.

For example:
- The `python3.9` file from `cpython-3.9.22+20250409-x86_64-unknown-linux-gnu-install_only.tar.gz` is only 21KB
- The `python3.9` file from `cpython-3.9.22+20250517-x86_64-unknown-linux-gnu-install_only.tar.gz` is about 47MB

I'm wondering why the size has changed so much. Can we reduce the file size as before, because it affects the size of our Docker images?
