I think the following would be sufficient:

1. Find small code which produces a reference to __enable_execute_stack even 
with -fno-stack-protector. Probably using a nested function should be enough.

2. Compile it to an object file, and run "nm -u object_file | grep 
__enable_execute_stack".

3. Write a test in aclocal.m4 using the above, and call it from configure.ac.

You can see many examples in aclocal.m4. If you have no clue on writing an 
autoconf test, I can write it for you, if you show me such code.
