updated ENC624j6net driver

- fixes to gcc native and cross compilation settings
  - implemented hardware based multicast filtering hashes, resulting
    in less unwanted traffic to our Amigas (especially Bonjour, UPNP and such)
  - MULTICAST option in envarc:sana2/enc624j6net.config will now
    allow all multicast traffic as opposed to the default fine grained
    filtering behaviour
