So if I understand, the above configuration is working well for you ?

Well, if the above configuration with a file:// path is working for
you, why don't you simply use this ?

I'm not sure to follow you here. As long as Buildroot is configured
with the Linux kernel package enabled, you can run "make
linux-menuconfig".

To be honest, I am quite puzzled by your questions, so I believe there
is a misunderstanding somewhere.
