Log Message:
Note new distfile location, but use nbftp for now.

The new distfile has a bad name and doesn't have the auto* generated
files.  Given that it's on github, these issues are not likely to be
fixed.  There has been no upstream release since 2008, so there's
really no point in dealing with that until there is.  For now, just
use MASTER_SITE_BACKUP to avoid the old URL giving errors.
