printf() putchar() and friends, using
static FILE mystdout = FDEV_SETUP_STREAM(uart_putchar, NULL,
crash, when the code is compiled with -mint8. My tests run fine without

I suggest to add a guard against -mint8 to stdio.h
early, if this is nontrivial to fix.

#if __INT_MAX__ == 127
# error "stdio is incompatible with -mint8"
