How about the attached?

I've moved the syscalls, but left the machine overrides in place, I think.

We don't have an implementation for setjmp/longjmp yet, although we'll 
need to look into that when we build out more C++ support.  The register 
file on this architecture is "up to" ~64kB, depending on the thread 
configuration, and there's no well-defined ABI yet (just what the 
compiler implements), so it's trickier than average.

Once again, I've omitted the autogenerated files from the patch file. 
I've also changed to a commit message more in keeping with the new style.
