My PR 12946 removes libpython from distutils, python-config and
python-config.py:
https://github.com/python/cpython/pull/12946

Do you mean that this change will break the build of applications
embedding Python? If yes, what can done to fix that?

Provide a different script to the specific case of embedded Python? Or
add a new option to specify that you are embedding Python?

In Python 3.7, the required linker flag is "-lpython3.7m". It's not
trivial to guess the "m" suffix. FYI Python 3.8 it becames just
"-lpython3.8": I removed the "m" suffix which was useless.
