removing python 3.4 spews xargs usage errors

[Scott Moser]

i did a dist-ugprade, python3.4 got removed, I saw:

Removing python3.4 (3.4.4-1) ..
xargs: invalid number for -s option
Usage: xargs [OPTION]... COMMAND [INITIAL-ARGS]...
Run COMMAND with arguments INITIAL-ARGS and more arguments read from input.

Mandatory and optional arguments to long options are also
mandatory or optional for the corresponding short option.
  -0, --null items are separated by a null, not whitespace;
                                 disables quote and backslash processing and
                                 logical EOF processing

This happened for all of python3.4 libpython3.4-stdlib libpython3.4-minimal

I do not know whether or not it is failure, but it is at least odd looking.
