Hmmm, It looks indeed that it can happen only on already existing
directories, I can't reproduce neither with a new build, and not
everyone seems to be impacted by that bug neither, since some colleagues
did the same thing without any trouble (with a completely different
architecture though).

So it's not that bad.

However, when I do:

In my source dir
git checkout v3.9-rc1

In my build dir
ARCH=arm make clean
ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make zImage

And then it breaks.

So I suspect it's something not cleaned properly, or not generated
properly. Here is what's left after the make clean
