If the "-z noexecstack" option is not used the object is not tagged and 
is basically treated as "-z noexecstack".
When loading occurs if no objects have been tagged with "execstack" the 
stack is set to non-executable.
If only one object is tagged with "execstack" then it sets the stack as 
an executable stack.

I can put it back if you like.

Thanks for the review.
