This is due to Peter Trommler's D4009
(bd765f4b1332b3d2a7908de3f9ff1d50da0e0b1d). This changes the atomic
primops to use new GCC builtins available only in GCC 4.7 and later.
This version was released in 2012, so I thought we would be fairly safe
requiring it. This is another case where upgrading your Ubuntu
installation will help. That being said, we should certainly provide a
better error message, perhaps catching this in `configure` instead of
failing during the build.

We could also provide a fallback in the event that we are compiling with
an older gcc, although I'm not sure that this is worth the effort.

Cheers,

- Ben
