commit be645d7a9848847388a662f6c0f7571d52ed7a05 Author: Philippe Coval <philippe.coval@open.eurogiciel.org> Date: Wed Dec 17 16:46:29 2014 -0500 build: sort sources to build in a more deterministic way It has been observed that binaries contents are depending on the order of linked objects. This order is caused by GNU make's wildcard function and the position of sources on filesystem. This change tries to prevent this kind of randomness. Also consider building using -j1 flag to make it even more reproductible.
