If we change the test for _GLIBCXX_ATOMIC_BUILTINS to be smarter (in particular, it can simply be skipped whenever that target provides an implementation of the atomic functions) then we can fix the issue in a better way.

I think a better way would be to just remove the CXXFLAGS bits in acinclude.m4 when we do the test for builtin atomics. If the target can't deal with the atomics without special flags, skip. Not our problem.... that way we can fix 28671 and not have to re-open 24692.

Yeah, mine was just an idea...

Thanks a lot!

Paolo.
