Comment # 9 on bug 1031343 from Charles Arnold

If this issue is seen building Xen,

Traceback (most recent call last):
  File "gentest.py", line 6, in <module> 
    import random 
  File "/usr/lib64/python2.7/random.py", line 885, in <module>
    _inst = Random()
  File "/usr/lib64/python2.7/random.py", line 97, in __init__
    self.seed(x)
  File "/usr/lib64/python2.7/random.py", line 113, in seed
    a = long(_hexlify(_urandom(2500)), 16)
OSError: [Errno 38] Function not implemented

It is caused by a change in glibc 2.24 which in turn has introduced
a bug in python.

See http://bugs.python.org/issue29188

A patch is attached to that python bug.
