Subject: [PATCH] Add check for -latomic

Later versions of gcc on some architectures push atomic functions
out into a separate atomic library; add a check to see when this
is required and add it to LIBS if need be.

Specifically the problem was observed on GCC 4.8.2 on powerpc
architecture for Ubuntu 14.04:
