[pacman-dev] [PATCH] makepkg: Log commands to logfile

[Alain Kalker]

For debugging PKGBUILDs, and for reporting build failures upstream,
it is very important to know the exact commands that are executed
leading up to a problem.
By using `set -x` and an appropriate value for PS4, commands are
logged before they are executed.
