They are not longer part of the API and it can be done now.

I think tracing is not really interesting in the system startup 
sequence. It is single threaded with interrupts disabled. So, in case 
there is a problem, a classic debugger should be sufficient.

The general pattern for the system initialization via the linker set is:

static void constructor(void)


void some_public_api_func(void)
