When tracing functions is enabled this adds calls to __cyg_profile_func_enter() and __cyg_profile_func_exit() to the traced functions.
__cyg_profile_func_enter() and __cyg_profile_func_exit() invoke timer_get_us() to record the entry and exit time.
initr_dm() will make gd->dm_root = NULL and gd->timer = NULL, so timer_get_us() -> get_ticks() -> dm_timer_init() will lead to an indefinite recursion.
So select TIMER_EARLY when tracing got enabled.
