[Bug libstdc++/35816] libstdc++ built during bootstrap is pulling in host g++ support for atomic builtins

------- Comment #1 from oblivian at users dot sourceforge dot net  2008-04-03 17:34 -------
After looking back at my 4.2.3 build logs.  The above is somewhat incorrect. 
In 4.2.3, the pass 2 toolchain build of libstdc++ correctly checked the target
g++ rather than the host and reported that it would not use atomic builtins. 
It appears that this has changed in 4.3.0 or is an artifact of using sysroot
(which should not look at the host g++ for configuration options).
