 Per #8283, we need to check the hash of each file we download against the
 expected value. This should ensure that we never build without explicitly
 approving each new version _and_ a hash for each new version. It will also
 ensure that when an attacker tampers with the file on the remote server,
 we will not attempt to build likely hostile source bundles or load hostile
 extensions.

 I think I'll just write a simple macro to check all of the hashes after
 all the downloads complete. Does that seem like a reasonable approach?
