PS: With test_stable() one can tell implementations apart. If snrm2() is
implemented completely in single precision then the result of norm(a) will be
10000.0. If internally a double precision implementation is used but the result
is rounded to single precision then the result of norm(a) is 10000.5. Both
implementations are possible and probably present in different libs. Therefore
the test should allow for both results. It might produce some printed comment
about the implementation.
