I've found the issue. I had changed the python shell in order to add some trace options and that generated the issue. Removing the change did fix the issue. And, looking in depth at Avro results, I found that the final result is mixed with the traces, and that the result is OK.
So, that is my mistake. Sorry. Gonna close the defect.

Title:
  OptionParser on PPC64LE does not split args correctly

Status in “python2.7” package in Ubuntu:
  Invalid

Bug description:
  The issue appears on PPC64 LE.
  It is OK on (Ubuntu) x86_64.
  Version of Python is 2.7.6 on both systems.
  The issue is demonstrated while running AVRO Python tests (in lang/py : ant test).

  
  - On Ubuntu / PPC64 LE :

  $ pwd
  ..../lang/py
  $ export PYTHONPATH=./build/src
  $ /home/tony/AVRO/avro-FromFreshIBMSOEGitHub/lang/py/build/test/../scripts/avro cat /tmp/REIX --fields 'first, last'
  {"first": "daffy"}
  {"first": "bugs"}
  {"first": "tweety"}
  {"first": "road"}
  {"first": "wile"}
  {"first": "pepe"}
  {"first": "foghorn"}
  Usage: avro cat|write [options] FILE [FILE...]

  avro: error: Can't open last - [Errno 2] No such file or directory: 'last'
  $ echo $?
  2

  The issue is that 'first, last' is not parsed correctly. The white
  space between "," and "last" is parsed in a way that makes "last" been
  interpreted as a "FILE" instead of an option.

  
  Without the white space, that works fine:

  $ /home/tony/AVRO/avro-FromFreshIBMSOEGitHub/lang/py/build/test/../scripts/avro cat /tmp/REIX --fields 'first,last'
  {"last": "duck", "first": "daffy"}
  {"last": "bunny", "first": "bugs"}
  {"last": "", "first": "tweety"}
  {"last": "runner", "first": "road"}
  {"last": "e", "first": "wile"}
  {"last": "le pew", "first": "pepe"}
  {"last": "leghorn", "first": "foghorn"}
  $ echo $?
  0

  
  - On Ubuntu / x86_64, both 'first, last' and 'first,last' are OK:

  $ pwd
  ..../lang/py
  $ export PYTHONPATH=./build/src
  $ build/test/../scripts/avro cat /tmp/REIX --fields 'first, last'
  {"last": "duck", "first": "daffy"}
  {"last": "bunny", "first": "bugs"}
  {"last": "", "first": "tweety"}
  {"last": "runner", "first": "road"}
  {"last": "e", "first": "wile"}
  {"last": "le pew", "first": "pepe"}
  {"last": "leghorn", "first": "foghorn"}
  $ echo $?
  0

  
  Source code of: /home/tony/AVRO/avro-FromFreshIBMSOEGitHub/lang/py/build/test/../scripts/avro  is:

  def main(argv=None):
      import sys
      from optparse import OptionParser, OptionGroup

      argv = argv or sys.argv

      parser = OptionParser(description="Display/write for Avro files",
                        version="1.7.4",
                        usage="usage: %prog cat|write [options] FILE [FILE...]")
  ....

  So, OptionParser() does not work on PPC64 like it does on x86_64.
