That's because I avoid saying " .rel.dyn plus .dynsym" and just go for 
short ".rel.dyn" instead. Sorry for that.

Getting ".rel.dyn + .dynsym" overlay with ".bss" is exactly what the 
current linker file does, by emitting .rel.dyn, then .dynsym, then 
overlaying .bss back at the start of .rel.dyn. Look up a readelf -a of 
./u-boot and see where each section starts and ends.

If you find another way to do this overlay yet end up producing a 
different binary, I'll be interested in the result, but I honestly don't 
think you will find any.
