extconf: better check for GCC atomic builtins

Attempting to test for CMPXCHG on x86 should allow this check to
fail on i386 systems.  We also won't need try_run as a result,
enabling cross-compilation.  The configure.in check in Ruby
1.9.3 does something similar and that's far more widely used
than raindrops is.
