just a note --- there would also be at least 1 non-KnownFailureTest on amd64
(ran on my laptop) (failed on s390x as well):

======================================================================
FAIL: test_iv_cephes_vs_amos_mass_test (test_basic.TestBessel)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/usr/lib/python2.7/dist-packages/scipy/special/tests/test_basic.py", line 1656, in test_iv_cephes_vs_amos_mass_test

and majority of those s390x-specific failures seems to point to minpack.
so it might be that figuring out this bug would resolve quite a few failing
tests on s390x
