I'm fine with it, but IIRC the Rust support for most targets was pulled 
out as they weren't deemed ready to go yet.  If the Rust folks are OK 
turning on RISC-V support then it's fine with me, but I think it's 
really more up to them at this point.

So

in case folks want to take it via some Rust-related tree, but I'm also 
fine taking it via the RISC-V tree if that's easier.
