Hi! While working on the "reproducible builds" effort [1], we have noticed that tomsfastmath could not be built reproducibly. A list of object files is unsorted, which causes a non-deterministic linking order. The attached patch fixes this. Regards, Reiner [1]: https://wiki.debian.org/ReproducibleBuilds
