# DarkForge Linux — Phase 0, Chapter 6: Xz
# ============================================================================
# Purpose:  Cross-compile xz utilities (LZMA compression). Many source
#           tarballs use .tar.xz format, so this is essential.
# Inputs:   ${LFS}/sources/xz-5.8.1.tar.gz
# Outputs:  xz, xzcat, lzma etc. in ${LFS}/usr/bin/
# Ref:      LFS 13.0 §6.16
