I think there is a problem with libc. I just sent PR.
Using printf() with standard non-threaded libc causes errno set to 2.
Try the following:

#include <sys/errno.h>
#include <stdio.h>

void main(void)
{
	fprintf(stderr, "errno=%d\n", errno);
	fprintf(stderr, "errno=%d\n", errno);
	fprintf(stdout, "errno=%d\n", errno);
	fprintf(stdout, "errno=%d\n", errno);
}
