see, there you go!

No, we don't need to merge klibc to be able to develop and deliver
simple, kernel-developer-only userspace tools within the kernel tree.

Sam had a patchset which scoops up all the compileable .c files in
Documentation/ and actually puts them into a separate directory along
with a makefile.  It worked!  It didn't quite get merged though.
