kbuild: fix make incompatibility
"Paul Smith" <psmith@gnu.org> reported that we would fail
to build with a new check that may be enabled in an
upcoming version of make.
The error was:
Makefile:442: *** mixed implicit and normal rules. Stop.
The problem is that we did stuff like this:
config %config: ...
The solution was simple - the above was split into two with identical
prerequisites and commands.
With only three lines it was not worth to try to avoid the duplication.
