Comment (by mojca@…):

 Apart from blacklisting clang <= 425, a trivial `post-configure` patch
 would be to replace
 {{{
 #define HAVE_BUILTIN_ATOMIC 1
 }}}
 with
 {{{
 #undef HAVE_BUILTIN_ATOMIC
 }}}
 in `pyconfig.h`.

 (I added some other weird suggestions to the upstream bug tracker. Ideally
 the configure check should be improved, but I'm not sure how.)
