Arch Linux 2014.12.01 and Fedora rawhide (will be F22) now includes
Python 2.7.9 which turns on SSL certificate validation.  This leads to
to a problem: The Amazon S3 wildcard certificate specifies
*.s3.amazonaws.com which does not match any DNS-style buckets.  So you
have to use --no-check-certificate for operations on these buckets.
