Ignore the parts about the linker script, I disagree with you, but that's 
immaterial to my main point.  Your solution still is only an accidental 
one as you don't do anything about program headers but instead just add 
magic sections to magic places that happens to do what you want currently.  
That's not by design.


Ciao,
