unsorted input

Product: openSUSE Tumbleweed
Version: Current
Hardware: Other
OS: openSUSE 13.2

See also https://reproducible-builds.org/docs/stable-inputs/

When linking .o files in random filesystem order
the linker will vary the ordering of functions
and apply varying optimizations
resulting in binaries that differ on every build
and thus trigger rebuilds of depending packages
and are published to mirrors and users
when actually nothing really changed.
