BeagleBone CT-NG Tool Chain

Hello,

I am trying to build a cross tool chain for
the BeagleBone (white), rev A3. The problem I have
is the kernel header files; the kernel is from

https://github.com/beagleboard/kernel/tree/3.8

and no kernel later than the 2013-03-22 from that tree
can properly export its header files.

Is anyone using crosstool-ng to make a cross tool chain
for making the latest BeagleBone 3.8.4 kernel+modules?

I've look at using
https://rcn-ee.net/deb/wheezy-armhf/v3.8.13-bone43/linux-headers-3.8.13-bone43_1.0wheezy_armhf.deb
but I've not found a way to use that to successfully
build a crosstool-ng tool chain.
