[Buildroot] How can I install tkinter for python3 in Buildroot 2018.11.x ?

[Fame Castle]

Hello,

I have installed Buildroot from the GIT branch 2018.11.x . Everything works
as expected except python (3.7) having no tkinter installed.

There is this patch called "0017-add-an-option-to-disable-tk.patch":

I have tried to solve your issue using the below patch. Unfortunately,
it triggers a circular dependency, which I'm not sure how to solve at
this point:

Recursion detected for  : fontconfig
which is a dependency of: xlib_libXft
which is a dependency of: tk
which is a dependency of: python3
which is a dependency of: util-linux
which is a dependency of: fontconfig

We've already been bitten by this sort of circular dependencies in the
past, where the dependency of util-linux on python was a problem.

Here is the patch I have used:
