Custom Compile Fails

[Andrew Syrewicze <asyrewicze@gmail.com>]

Hey everyone. Went to compile my own kernel for my laptop today and ended up with some wierd errors that caused make-kpkg to die. 

My goal with this kernel was size, I wanted it to be lean, and i'm wondering if i left some key component out of the config file. 

Here is the error output.

Does anybody have any ideas???
