IIRC the struct is droped by the garbage collector as it's never used

the idea is to compile it always but drop it is not used

without the option

# ls -al build/tny-a9263/barebox.bin 
-rwxr-xr-x 1 root root 259056 Apr 12 18:29 build/tny-a9263/barebox.bin

with it
# ls -al build/tny-a9263/barebox.bin 
-rwxr-xr-x 1 root root 259960 Apr 12 19:45 build/tny-a9263/barebox.bin
