# DarkForge Linux — Phase 0, Chapter 6: Binutils Pass 2
# ============================================================================
# Purpose:  Rebuild binutils with the temporary toolchain. This produces
#           binutils that runs on the target and generates code for the target.
#           Pass 1 ran on the host; Pass 2 runs on the target (via cross-compiler).
# Inputs:   ${LFS}/sources/binutils-2.46.0.tar.xz
# Outputs:  Updated binutils in ${LFS}/usr/
# Assumes:  All Chapter 5 + Chapter 6 temp tools (006-020) complete
# Ref:      LFS 13.0 §6.17
# ============================================================================
