[Dev] crosstool-ng-libre

[Josh Branning]

Hello,

I have received a laptop, on which I intend to cross-compile the 
parabola base packages, using crosstool-ng-libre, on debian. The idea, 
is that it will be possible to create something like 'parabola from 
scratch', and could help with reproducible builds.

When I wrote the patch for crosstool-ng-libre, I only tested to see if 
it would download the linux-libre kernel instead of the vanilla kernel. 
Unfortunately, upon further, recent, testing, I found that the compiling 
process for the toolchain breaks when attempting to patch the kernel.

So here is the updated patch. Which has been successfully tested to see 
if it can build a complete toolchain.

BRgs.

Josh
