I'm happy with the RISC-V aspects, which I understand to be functionally a NOP.  
I like avoiding the ABI bloat.

For some reason I thought someone mentioned some references to _init/_fini 
floating around our port, but I can't find any so maybe I'm just going crazy?  
If they're there then we should probably remove them, as they don't actually do 
anything.
