[RFC]: target.make simplification

[Adam Fedor]

I've tried to simplify the TARGET_SYTEM_LIBS here since almost every 
system uses the same thing. Looks ok?
2003-07-19  Adam Fedor  <fedor@gnu.org>

        * target.make: Set thread library in AUXILIARY_OBJC_LIBS. Set
        reentrant flags for all targets if threaded. Remove duplicates.
