sort input files

[bmwiedemann]

when building packages (e.g. for openSUSE Linux)
(random) filesystem order of input files
influences ordering of functions in the output,
thus without the patch, builds (in disposable VMs) would usually differ.

See https://reproducible-builds.org/ for why this matters.

I tried, but both of their mailservers produce timeouts from my mailserver IP 144.76.96.7

so I would be happy if someone could relay the patch for me.
