I run the rust tests with whatever's the rust compiler that comes
with Fedora:

 $ rustc --version
 rustc 1.13.0 (2c6933acc 2016-11-07)

I assume others that run Fedora do the same, since I assume
the instructions to set up for gdb testing on Fedora pull
in rustc [1].  So I guess the bots are testing rust too?
(I'm still on F23, should really upgrade...)
