[PATCH] supply '-n' to gzip to produce identical tarballs

Without the '-n' ('--no-name') argument, gzip includes timestamp in output which results in different files. Important systems like FreeBSD ports and perhaps many others hash/checksum downloaded files to ensure integrity. For projects that do not release official archives, gitweb's snapshot feature would be an excellent stand-in but for the fact that the files it produces are not identical.

Supply '-n' to gzip to exclude timestamp from output and produce idential output every time.
