"libstdc++: Rewrite atomic builtin checks [PR70560]", for both GCN, nvptx
we now get:
+configure:16060: checking for atomic builtins for _Atomic_word
+[...]
+configure:16073: result: yes
..., and thus may revert the 'atomicity_dir=cpu/generic/atomicity_builtins'
hard-coding added in commit 059b5509c14904b55c37f659170240ae0d2c1c8e
"GCN, nvptx libstdc++: Force use of '__atomic' builtins [PR119645]".
