Bug#889860: python3-numpy: TypeError initializing resolution on powerpcspe

["Aaron M. Ucko" <ucko@debian.org>]

Package: python3-numpy
Version: 1:1.13.3-2
Severity: normal
Tags: upstream
User: debian-powerpc
Usertags: powerpcspe
Control: affects -1 src:chemps2

As observed in [1], numpy encounters two warnings and a type error
when initializing itself on powerpcspe:

  /usr/lib/python3/dist-packages/numpy/core/getlimits.py:82: RuntimeWarning: overflow encountered in power
    self.resolution = float_to_float(float_conv(10) ** (-self.precision))
  /usr/lib/python3/dist-packages/numpy/core/getlimits.py:82: RuntimeWarning: invalid value encountered in power
    self.resolution = float_to_float(float_conv(10) ** (-self.precision))
  Traceback (most recent call last):
    File "setup.py", line 22, in <module>
      import numpy as np
    File "/usr/lib/python3/dist-packages/numpy/__init__.py", line 142, in <module>
      from . import add_newdocs
    File "/usr/lib/python3/dist-packages/numpy/add_newdocs.py", line 13, in <module>
      from numpy.lib import add_newdoc
    File "/usr/lib/python3/dist-packages/numpy/lib/__init__.py", line 8, in <module>
      from .type_check import *
    File "/usr/lib/python3/dist-packages/numpy/lib/type_check.py", line 11, in <module>
      import numpy.core.numeric as _nx
    File "/usr/lib/python3/dist-packages/numpy/core/__init__.py", line 51, in <module>
      from . import getlimits
    File "/usr/lib/python3/dist-packages/numpy/core/getlimits.py", line 226, in <module>
      tiny=exp2(_ld(-1022)))
    File "/usr/lib/python3/dist-packages/numpy/core/getlimits.py", line 82, in __init__
      self.resolution = float_to_float(float_conv(10) ** (-self.precision))
  TypeError: unsupported operand type(s) for ** or pow(): 'numpy.float128' and 'int'

Could you please take a look?

Thanks!
