build: add libatomic dependency for 32-bit clang
[ upstream commit c649f0b4f58e35730d773104d3ba93bf21e21505]
When compiling with clang on 32-bit platforms, we are missing copies
of 64-bit atomic functions. We can solve this by linking against
libatomic for the drivers and libs which need those atomic ops.
