This libatomic issue is problematic for packages using cmake. libatomic
is automatically added to the link process when thread support is
enabled, ie when linking with -pthread. However cmake insists in linking
directly with the thread library using -lpthread, which doesn't enable
full thread supports (as another example it doesn't define __REENTRANT
on GNU/Linux or _MT on Solaris).

This can usually be fixed by looking for "FIND_PACKAGE(Threads)" in
CMakeLists.txt files and adding "set(THREADS_PREFER_PTHREAD_FLAG ON)"
before.
