安裝S2E時安裝multiprocessing包出錯

報錯信息如下：

ERROR: Complete output from command python setup.py egg_info:
    ERROR: Traceback (most recent call last):
      File "<string>", line 1, in <module>
      File "/tmp/pip-install-n463ate5/multiprocessing/setup.py", line 94
        print 'Macros:'
                      ^
    SyntaxError: Missing parentheses in call to 'print'. Did you mean print('Macros:')?
    ----------------------------------------
ERROR: Command "python setup.py egg_info" failed with error code 1 in /tmp/pip-install-n463ate5/multiprocessing/

解決方案：

對安裝的腳本做如下修改
