# Purpose:  Run all toolchain build scripts in sequence with logging.
#           This is a convenience wrapper that executes each script,
#           logs output, and stops on any failure.
# Inputs:   LFS environment variable, all source tarballs downloaded
# Outputs:  Complete cross-toolchain and temporary tools
# Assumes:  Running as 'lfs' user (scripts 001-022), root for 023+
