bpo-36302: Sort list of sources (GH-12341)
When building packages (e.g. for openSUSE Linux)
(random) filesystem order of input files
influences ordering of functions in the output .so files.
Thus without the patch, builds (in disposable VMs) would usually differ.
Without this patch, all callers have to be patched individually

but that is an infinite effort.
See https://reproducible-builds.org/ for why this matters.
