Here is an example script generated for the example logfile (for RRTL;DR:)
---[file: clean-build.sh]---
#!/bin/bash

# replay-build.sh - Replay commands from a makepkg logfile

# This script was created using the following configuration:
# Log file: libxcb-1.9.1-1-x86_64-build.log
# Build settings: /etc/makepkg.conf
# Debug build: no

# Example usage:

# $ cd <directory containing PKGBUILD>
# $ rm -rf pkg src
# $ mkdir pkg src
# $ makepkg -o
#
# Do a clean build or install
# $ cd src/<top of source tree>
# $ ../../replay-build.sh 2>&1 | tee 
../../libxcb-1.9.1-1-x86_64-build.log.clean
#
# Then compare the logs
# $ cd ../..
# $ diff -u libxcb-1.9.1-1-x86_64-build.log{,.clean}

Clean, concise, easily adaptable for submission upstream, methinks.

Kind regards, Alain
