Dear Maintainer, While working on the “reproducible builds” effort [1], we have noticed that 'gdal' could not be built reproducibly. Either one of the two attached patches fixes the order files are passed to libtool — but I don't know if one of them could be an acceptable solution. One applied, gdal can be built reproducibly in our current experimental framework. Regards, Alexis Bienvenüe. [1]: https://wiki.debian.org/ReproducibleBuilds
