Routine updates to the latest stable versions, to keep in lockstep with (some) distros.

Tarballs:

• https://github.com/ivmai/libatomic_ops/releases/download/v7.6.10/libatomic_ops-7.6.10.tar.gz

I'm testing on Cygwin; don't anticipate any serious problems (though we need to do gc and libatomic for #27330).
