RE: [Testsuite] getpid in gcc.c-torture/execute/pr58419.c

Hi,

	* gcc.c-torture/execute/pr58419.c: Adjust the test to work with bare metal targets. The 
           test code references to functions that is not implemented for the avr target (getpid()).

Thanks,
Soundararajan

You want to avoid the printf.  Instead I think a dummy function that is
marked as noinline should be sufficient -- I just haven't had the time
to verify that myself.
