The synthetic target tries to emulate an embedded system. A typical
embedded system runs forever, barring power failures, crashes leading
to watchdog timeouts, or similar unusual events. Hence by default the
synthetic target will do the same.
If you want your application to exit back to the shell prompt then
call cyg_hal_sys_exit(0). That call only exists on the synthetic
target. If you then want to move your application on to a real
embedded system you will have to do something different.
