ARM (Raspberry Pi) results

[pqnelson]

I just wanted to let you know, I tested this on a Raspberry Pi 4, and it appears to work with GCC, Clang, and TCC. They all end up having NANBOX_32 and NANBOX_UNIX both defined to 1 (I added some code to print out the values of these various macro constants at the beginning of main() in test.c).

I'm going to try to get the 64-bit Raspbian OS soon-ish, I'll add results for that OS if/when I get around to it.

GCC Results
