Flush 'Build for ...' messages before each build

During a run of 'auto_build.py', stdout buffering get taken over by the
subprocess module, causing print statements in 'auto_build.py' to not
output until the very end of a build. Calling 'sys.stdout.flush()'
causes stdout to be output before the next call to 'subprocess'.
