Reading this, I am not sure your fix is correct (though I am not sure
what the correct fix is).

Indeed, in this bug report, Victor Stinner explains:

"""
There are two use cases for libpython:

* Build a C extension and load it in Python: use case called "pyext" by waf
* Embed Python into an application: use case called "pyembed" by waf
"""

The first case should not require -lpython3.8, and therefore
python-config no longer returns -lpython3.8, unless you pass --embed
(which means you are in the second case: you embed Python into an
application).

But kmod is only providing Python bindings: it's a C extension to be
loaded in Python, so we are in the first case, and we shouldn't need
--embed.

What do you think ?
