My PR 12946 removes libpython from distutils, python-config and

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.

Night gathers, and now my watch begins. It shall not end until my death.
