[Qemu-devel] [PATCH 3/4] qapi-types.py: Fail gracefully if out dir is not specified

[Luiz Capitulino]

Otherwise we get:

Traceback (most recent call last):
      File "./scripts/qapi-types.py", line 183, in <module>
          os.makedirs(output_dir)
        File "/usr/lib64/python2.7/os.py", line 157, in makedirs
          mkdir(name, mode)
      OSError: [Errno 2] No such file or directory: ''
