Mark AESNI files as not needing executable stacks

Some Linux systems now come with facilities to mark the stack as
non-executable, making it more difficult to exploit buffer overrun
bugs.  For this to work, object files built from assembly need a
section added to note whether they require an executable stack.

Patch from Dhiru Kholia with comments added.  More information at:
