0791c940ad * ruby_atomic.h: use __atomic builtin functions supported by GCC. 
__sync family are legacy functions now and it is recommended
  that new code use the __atomic functions.
  http://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html

* configure.in: check existence of __atomic functions.
