We're ALREADY talking about an ABI incompatibility.  How does it make
more sense to hide this incompatibility in some random magic section?

What has this got to do with anything?

I see ZERO difference between your note section and using a bit
in the e_flags.  Except that yours is more convoluted, and less
obvious that it is NOT advisory, unlike the execstack bit.

Please do not bother posting your patch again until the larger
community has come to some consensus on this point.
