Using __sync_fetch_and_add_8 on architectures without native support
requires the libatomic library
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56300), which is part of
GCC 4.8+.
The attached patch links against this library and forces compilation
with gcc/g++ 4.8. It also disables --as-needed on ia64 to work around
bug #718047.
This should fix everything except armhf (crashing make, which is a bug
there not here), but has not been tested.
