For what it's worth, I (at least used to) build qemu regularly on Arch
Linux and the only issue I encountered with this is that the iotests
wouldn't work.  As a workaround, I made the check script detect that
interpreter line and just run the script through the interpreter
configured through --python, so it works now...

So from what I could tell, everything worked when you specify
--python=python2.
