[Libre-soc-sim] NLnet grant request, draft

[Peter Hsu]

I cannot run the same binary on spike because it only works for programs 
linked with newlib.  Uspike/caveat works with libc which you need to get 
pthread, OpenMP, MPI, etc. to work (original reason I built caveat for 
riscv).

I suspect the problem has to do the base of the stack--gdb probably 
expects something specific telling it this is the oldest stack frame and 
to stop the backtrace.  I remember there was something called 
"frame_dummy" I had to fool around with many years ago...
