The Python binary now builds the libpython static library using
"-Wl,--whole-archive" or "-Wl,-all_load"linker option to
export all symbols exported by object files.
Previously, the "Py_FrozenMain" symbol was not exported.

I tested this PR in my centos vm and it has passed.
Due to lack of the MacOS, I haven't test the -all_load link option for lacking of macos.

I suggest to not use libpython.a to build the python executable, but pass directly the long list of object filenames (.o).

OK, it's would be more direct.

I wrote PR #30556 to propose my idea.

The problem of this approach is that the -Wl,--whole-archive flag is not portable. That's why you had to use -Wl,-all_load for example.

I wrote a different approach which simply skips the static Python library: GH-30556.
