build: Add a way for auto_build.py to print actions without executing

[Mats Wichmann]

EXEC_MODE={one of: False, false, 0} python auto_build.py args
will print what the script would do without actually running the actions
Found it hard to keep track of all the different targets,
this is a quick way to report.

[Philippe Coval]

Port from master to 1.3-rel
