D mention and mini-demo at FOSDEM in the RISC-V room

[Iain Buclaw]

In-case it was missed, D running on RISC-V was used as part of a 
small demo (taken from https://dlang.org/wc.html) at FOSDEM last 
month in the Fedora Rawhide talk.

Of other note, a couple of items in the Few (potentially 
annoying?) bits slide were discovered when I was porting D 
runtime with David.
