Building Python as a macOS framework fails on macos >= 15.4

[erikjv]

Bug report

Bug description:

When building as a framework, a duplicate -rpath option is specified when linking the Python "shared library" as well as when linking python.exe. Since macos 15.4, the dyld will reject all duplicate paths, meaning that python.exe cannot find the Python shared library, and the build fails.

Below is the last bit of the build output, including the failure to run python.exe.

Note: this happens on both Intel and Apple Silicon. The output below is while building on Intel.
