No, not at all. That's the point of putting it in the linker script and 
letting the linker compute the address.

And that is exactly what this does.  Take a look at the linker script 
and how it works.  All my addition does is declare a named section that 
starts at exactly the place that your __user_prog_start symbol is 
defined.  It's really your solution, but with an additional name that 
you can use as an attribute to a data section.
