It doesn't work on current ARM32 chips either, but no one has complained
about the existing coding. At least on ARM64 there'd be a likelihood
that you'd get an assembler error rather than an executable that crashes
at launch.
I suppose we could consider adding
#ifdef __aarch64__
#error ...
#endif
in the section for not-HAVE_GCC_INT_ATOMICS, but I'm doubtful it's
worth the trouble.
