* Added the j2sdk of Sun for Linux. Downloading this thing is

          a big problem, so I decided to require to user to get the
          file and put it in some location in the file system. wget
          doesn't seem to accept the file scheme however, so I had to
          move the copying into the builder itself. The builder checks
          the md5 hash of the downloaded file. Maybe having a separate
          'fetchfile' would be useful to make a file in the outside
          world pure. I tried to add this to build-support, but this
          obviously did not work. I still committed it. Just remove it
          if you think that it sucks.
