Compiling on Fedora 32 using Python 3 fails

[Finnboy94]

With soundrts 1.3.5, trying
python setup.py build
on Fedora 33 gave this error:
[user@palvelin soundrts]$ python setup.py build                               
Traceback (most recent call last):                                             
  File "setup.py", line 31, in                                         
    TMP = os.environ["TMP"]                                                    
  File "/usr/lib64/python3.8/os.py", line 675, in getitem                  
    raise KeyError(key) from None                                              
KeyError: 'TMP'

That's to say, Fedora 32.

At the moment, setup.py is only supposed to build the Windows executable.
It should be possible to launch the game with a "python soundrts.py" command.
