kbuild: better cleaning
Let make clean delete generated dot-files and .o files.
Introduce distclean/mrproper that deletes .config, linux symlink
and all files left behind by editors and patch.

Hi Peter
In following patch I did not make a difference between mrproper and
distclean. I only added mrproper because I'm used to it from the kernel.
Also I did not put in .hg directory, SCCS and others. I doubt people use
it for klibc anyway, but it easy to ignore these too.
I recall I tested make clean and I cannot see how I have missed
all the *.o files. Maybe cogito played me a trick?
Anyway I learned to use git ls-files --others
