[Boost-build] Incorrect exit status if process abends

Hi,

There's a problem in execunix.c where I don't set the correct process  
termination status if the process crashes or otherwise fails to exit  
through normal channels (by calling exit() or_exit(), or exiting  
through main).  This patch marks the process termination status as  
having failed if it doesn't exit through normal channels.

If there's no objection, I'll get this committed to trunk.
