Fixes for Solaris-2.4/sparc dynamically linked binaries. 

We can now run them, but:

1. setcontext() causes a panic so binaries that receive signals
   crash the machine [something is wrong with the register setup].
   sleep 10 ==
    Watchdog reset
    Data Access Exception
    Type  help  for more information
    ok

2. csh says "unknown software trap a7".
3. ls gives us a bus error.
4. ldd works :-)

But I solved the problem that had been bothering me for weeks :-)
