linux-headers-am33x-lagacy missing arch/arm/tools

[Phosfor]

Hi everyone.

I want to make a custom kernelmodule for my BeagleBone (white).
I'm running the 3.8.13-legacy kernel so I installed linux-headers-am33x-lagacy with pacman.
Then I did
$this->bbcode_second_pass_code('', 'cd /usr/src/linux-3.8.13-38-ARCH
su
zcat /proc/config.gz > .config
make prepare')

The last command outputs the following:

$this->bbcode_second_pass_code('', '[root@beaglebone linux-3.8.13-38-ARCH]# make prepare

Ignoring the warnings it says arch/arm/tools/Makefile is missing.
So I checked and there isn't even the folder tools in arch/arm.
I tried downloading the (3) files from kernel.org. This time make prepare worked but make modules_prepare was still missing other files.

I'm wondering:
Is there something I'm doing wrong? Do I have to change the config?
Is this package not intended for compiling kernel-modules? But then again what is it's use?
Or is this a bug of the header-package?

Ok turns out I don't need to make modules_prepare.

And the reason I tried to do this was my bad. I just made a typo in my Makefile
