Bug#917095: python3-pyfftw: alignment tests fail on several arches

[Drew Parsons]

Package: python3-pyfftw
Version: 0.11.1-1
Severity: normal

Alignment tests fail on many arches (armel, armhf, mipsel; also
riscv64, sparc64). So pyFFTW shouldn't be shipped for these arches
until the problem is fixed upstream. 

Sample errors include:

ERROR: test_get_alignment (test.test_pyfftw_utils.UtilsTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "test/test_pyfftw_utils.py", line 85, in test_get_alignment

Upstream is aware of the problem,
