According to the latest test results, it looks like python.jam is
adding an extra -lpthread :(. 

So I can remove that, but it also is not adding any of -lresolv,
-lsocket, or -lnsl.  The earlier error messages seemed to indicate
that it was OK.  I wonder why?  I'm inclined not to add them to the
jam file in case some other sunos installation complains like yours
did about -lpthread.
