[Buildroot] No rule to make target 'host-python !!

Sun Jan 24 21:27:06 UTC 2021

You are right Peter!
You will find my python pakage joined.
Like I told you I am noob in kernel compil, so sure I made bad thing, but I
am here to learn.

So if I well understood even if I didnt select the package in menu config,
config.in and .mk file interferes with the build..
I use some other config.in and .mk file as model to build these file for my
package, so I make a mistake, if you could look them ?

Regards

(I remove the tar file in files directory cause it is to heavy to send, but
it's just python37 archive)
