OK, having dug a bit deeper, I now have a feel for what these extra files are. More importantly, I see that builtins.c has a dependency on the target OS in __num_cores(). This suggests that the target (without extensive work) does need to be specified at ISPC compile time - not just run-time. Hence, I will build the 1.9.2 of ISPC from source and then make minimal changes to target GCC/Linux and rebuild. Fingers crossed it will all be good!
