One reason that comes to mind is that what appears below main is 
starting to get a little out of control.  In the good old days, nothing 
appeared below main because there was simply nothing there.  The may not 
have even had an entry point since crt0.o always came first.  Now, well ...

Perhaphs the correct fix is to let the user decide.  Add a ``set 
stack-bottom-strategy ....''  :-)
