Build in C++11 mode on Unix-like bots.

Mac and Windows bots are already building in C++11 mode.
This turns on the rest, mostly to see what work remains.

This will probably break a few bots.  It'd be nice if we could let those
all come in as red before reverting this so I can see the full list to fix.
