RFC: svn for make fetch

Creating deterministic tars (ignoring "metadeta") sounds like it
should be a solved problem by now. If it isn't then I will have to
make it my next project ;)

Anyway lets take your script above modify it so that it uploads the
tarball to freebsd mirrors and includes the checksum as of the time
the maintainer created the tar. This would be much closer to my
proposal.
