Nobody disagrees.  The execstack functionality is exactly there to avoid
having an executable stack unless really needed.  To to this binaries
need to be marked appropriately and the defaults (what happens if the
status isn't known for a file) have to be selected correctly for each
platform.  See Jakub patches to ld, see the extra section gcc creates to
mark stack usage (.note.GNU-stack).
