Bug#813309: lapack: please make the build reproducible

Hi!

While working on the "reproducible builds" effort [1], we have noticed
that lapack could not be built reproducibly.
It includes a log file of test results (testing_results.txt), which
includes measured run times of the tests.
The static library libblas.a can also contain objects in a different
order, depending on the configured locale.

The attached patch removes the test log, as it provides no value
to the user, and sorts the files packed into the static library
locale-independently.

Regards,
 Reiner
