# DarkForge Linux — Phase 0, Chapter 5: Binutils Pass 1
# ============================================================================
# Purpose:  Build the cross-assembler and cross-linker (binutils) as the
#           first component of the cross-toolchain. This must be built first
#           because both GCC and Glibc configure tests depend on it.
# Inputs:   ${LFS}/sources/binutils-2.46.0.tar.xz
# Outputs:  Cross-binutils installed to ${LFS}/tools/
# Assumes:  Running as 'lfs' user, environment sourced from 000-env-setup.sh
# Ref:      LFS 13.0 §5.2
# ============================================================================
