Hi,

I like starting my messages with something like 'hi', 'hello' or 'yo
guys'. I don't know exactly why. Maybe... respect. And this even if my
response is not the right one.

Have you try :

>$ make -C package/config clean

Seems you have updated some of your tools without having cleaned your
half-built buildroot.
