Generate a distribution tar file for unbound.

    -h           This usage information.
    -s           Build a snapshot distribution file.  The current date is
                 automatically appended to the current unbound version number.
    -rc <nr>     Build a release candidate, the given string will be added
                 to the version number 
                 (which will then be unbound-<version>rc<number>)
    -d SVN_root  Retrieve the unbound source from the specified repository.
                 Detected from svn working copy if not specified.
    -wssl openssl.xx.tar.gz Also build openssl from tarball for windows dist.
    -wxp expat.xx.tar.gz Also build expat from tarball for windows dist.
    -w32	 32bit windows compile.
    -w ...       Build windows binary dist. last args passed to configure.
