This?

#elif COMPILER(GCC) && !CPU(SPARC64) && !OS(SYMBIAN) // sizeof(_Atomic_word) != sizeof(int) on sparc64 gcc
#define WTF_USE_LOCKFREE_THREADSAFEREFCOUNTED 1

inline int atomicIncrement(int volatile* addend) { return __gnu_cxx::__exchange_and_add(addend, 1) + 1; }
inline int atomicDecrement(int volatile* addend) { return __gnu_cxx::__exchange_and_add(addend, -1) - 1; }

in src/3rdparty/webkit/Source/JavaScriptCore/wtf/Atomics.h

Please note that we deliver only 32 bit Qt

However, the test is overzealous because gcc 4.8 supplies an
implementation for sparc v9. We'll see this when we deliver a 64 bit Qt.
