This is probably caused by
kernel: make the kernel build auto-clean the build dir like package builds
https://git.lede-project.org/?p=source.git;a=commitdiff;h=22ef1c83b35cd5633b0c58c9c38a43494a906a6a
(as some pointed to me).

Felix: is this possible to limit auto-cleaning to track changes in
patches-*/ files-*/ and files/ only? So e.g. changing something in
base-files or config-* won't trigger it?
