Detailed Description

Pre-build configuration checker for the kernel build system.

This script checks for required tools, verifies compiler and linker flags, sets up directories, clones needed dependencies, and prepares the environment for building.

Run this script before running the actual build (./build.py). Use --reconfigure to force regeneration of the didconf file.
