NAK NAK NAK

This now means I can no longer run selftests, I thank you very much! :-/

root@spr:/usr/src/linux-2.6# make O=defconfig-build/ -j64
make[1]: Entering directory '/usr/src/linux-2.6/defconfig-build'
***
*** The source tree is not clean, please run 'make mrproper'
*** in /usr/src/linux-2.6


I've always done:

  cd tools/testing/selftests/x86; make

and that has always worked

Now I can't bloody well build *any* selftest or risk not being able to
do builds.
