Subject: [PATCH] common/mltools: make sure machine readable output is flushed
Enhance the helper printf function for machine readable output to always
flush after each string: this way, readers of the machine readable
stream can get the output as soon as it is outputted.
(cherry picked from commit abf1607f46ddc3d829a3688b9499a9bcd2319d19)
