Hi,
I'm compiling the kernel for an iMX28(ARM) board, and since 3.9-rc1, I
get the following error at compilation time:
make[3]: *** No rule to make target
`/home/max/Work/2012/crystalfontz/rewrite/linux-dt/include/config/hz.h',
needed by `kernel/hz.bc'. Stop.
I'm doing a clean out-of-tree build, with the following configuration
file: http://code.bulix.org/m4y7se-83102?raw
Reverting commit 1b66e0fd ("kernel: Replace timeconst.pl with a bc
script") make the compilation go on as usual.
Thanks,
Maxime

That file should have been created by "make *config", and I just
verified that it does indeed do so. That file is a sentinel for
configuration changes; the entire build system depends on it.
I am not sure what you mean with "clean out-of-tree", however.
kbuild people: is there anything wrong with how this dependency is
specified?

I triggered this issue when switching to 3.9-rc1, and oldconfig runs at
that time, and now, running menuconfig doesn't generates it either.

make O=$(pwd) -C /path/to/linux/source some_configs
make

Can you give the exact set of commands you are running when you see
this? I cannot reproduce this no matter what I do, and it doesn't seem
like it is being a common problem.
In the example above the first "make" command does indeed not create any
files in include/config, but they get created immediately on the second
"make"...

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
