Hi! While working on the "reproducible builds" effort [1], we have noticed that mdp-src could not be built reproducibly. During build it links object files in non-deterministic order. The attached patch fixes this by sorting the list of source files. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
