Dear Maintainer, While working on the “reproducible builds” effort [1], we have noticed that 'openblas' could not be built reproducibly. The attached patch fixes the order files are passed to `ar' and gcc. Once applied, openblas can be built reproducibly in our current experimental framework. Regards, Alexis Bienvenüe.

Description: Order files Order the files when calling `ar' or $(CC), to make the build reproducible.
