Jake Petroules cd542a82b0 Remove references to obsolete platforms
ultrix and reliant have not seen a release since 1995. dgux not since
2001. bsdi not since 2003. irix not since 2006. osf not since 2010.
dynix... unclear, but no later than 2002. symbian needs no mention.
All considered obsolete, all gone.

sco and unixware are effectively obsolete. Remove them until someone
expresses a real need.
