``setup.py`` no longer defines ``Py_BUILD_CORE_MODULE``. Instead every module defines the macro before ``#include "Python.h"`` unless ``Py_BUILD_CORE_BUILTIN`` is already defined. ``Py_BUILD_CORE_BUILTIN`` is defined for every module that is built by ``Modules/Setup``. Signed-off-by: Christian Heimes <christian@python.org>
Makefile and makesetup already define ``Py_BUILD_CORE_BUILTIN`` and include ``Modules/internal`` for us.

LGTM. I compared the list of modified files to setup.py. It seems like the PR is exhausitve.
Oh. I didn't know that Modules/makesetup already uses the correct flags for build C extensions depending if it's before or after *shared* in Modules/Setup:
PY_BUILTIN_MODULE_CFLAGS= $(PY_STDMODULE_CFLAGS) -DPy_BUILD_CORE_BUILTIN
PY_CORE_CFLAGS= $(PY_STDMODULE_CFLAGS) -DPy_BUILD_CORE
