MLECO-1948: Fix for SysTick init and GNU's stdout

The counter val could have been 0 when read the first time
quickly after the init function. The init function will now
wait for the SysTick counter to start before returning.

Also included are some minor changes to get around  GNU's
file stream implementation being line buffered.
