Default [Q] Help with compiling custom kernel

Trying to build a kernel in particular Franco for Nexus 5 (hammerhead)

So I made a folder and I git clone this repository.

https://github.com/franciscofranco/hammerhead

I did a make config and I have 1k of options. Am I building the options for the Linux kernel? I figured that was already configured.

Do I need to build this kernel with a toolkit Linaro?

Any help or directions would be great! Thanks!
