Subject: Add include to config.g

Usage:

include path

path can be relative to the current directory or absolute starting at /src.

I tested it with:

include /config/absolute.lb
include relative.lb

in /src/northbridge/amd/amdk8/Config.lb
which included
   /src/northbridge/amd/amdk8/relatvie.lb
   /src/config/absolute.lb
