I tried to reproduce this here without luck.
The tests performed by kbuild to dertermine if the
source directory is clean are very basic.
If the file .config exist or the directory
include/config exists then the source tree is considered clean.
Otherwise you get the above message.

Can you please try to run: make mrproper
and then manually check if the .config file
or the include/config directory exists.

If they exists after make mrproper then
check your permissions.

In any case let me know the result.
