Added a couple of new lines to support icedtea-6 and icedtea6-bin on SPARC
Please note that this is a proposed enhancement. Feel feel to correct me if I'm wrong. Also see bug 159780.
Since bug 308513 is fixed, it would be good to have ppc/ppc64 magic for icedtea-6* too, pretty, pretty please :)
I'll see what I can do, but bear in mind I'll need a larger HDD for my PPC before I can weave my magic over icedtea :)
Fixed in virtual/jdk-1.6.0-r1.
Closing as adding sparc to KEYWORDS is a separate bug.
