Yes, the image file is architecture independent. At the moment, the
SystemTracer is not working correctly with it runs on little-endian
platforms, and the image files that it produces are broken if the
SystemTracer is run on a little-endian box. I seem to recall reading
that this is a known shortcoming, but I don't recall where I read
this or if anyone is working on it.

I've tried changing #writeFileHeader to produce architecture-neutral
image file headers. This was the part that was obviously broken, but
I have not been able to produce a working image, so presumably there
are some other issues to address, or maybe I just "fixed" it wrong.

Anyway, that's all I know about the issue, so if anyone else has
gotten the SystemTracer working on an Intel box, please speak up.
