macos: pipe input doesn't work with scanf

[Emoun]

To send input to a program's stdin running on the simulator, we can use piping: echo "some input" | pasim a.out.

Doing this on macos doesn't work. Example program:

#include <stdio.h>
int main() {
	int x ;
	scanf("%d", &x);
	printf("Output: %d\n", x + 2);
	return 0;
}

After compiling with patmos-clang -O2 main.c, and running using echo "2" | pasim a.out, we would expect it to output Output: 4, but instead we get Output: 2.
Clearly scanf is not working correctly.
Running the same program and commands on ubuntu outputs the expected string

Could this be related to t-crest/patmos#85 ?

Wow, that difference between macos and Linux? The above-mentioned issue is reported on patemu instead of pasim. But maybe they are related. And in newlib instead of the two simulators.
