The build was failing on some machines because of a find command that
touched files in different orders on different machines.

That confused makes timestamp mechanism.

    • macOS

  • Tested execution of all binary files (usually in ./result/bin/) (at least /bin/sage)
  • Fits CONTRIBUTING.md.

The build was failing on some machines because of a `find` command that
touched files in different orders on different machines.

That confused `make`s timestamp mechanism.
