Yes it's been suggested by Stafford here:

Ok, so it fixes this bug for Buildroot toolchain and you'll provide 
Bootlin toolchain and we can consider this bug as not affecting
Buildroot anymore. The chance one would use an external OpenRisc 
toolchain would be very rare. Right?

Then we could revert commit:
"package/protobuf: disable package if binutils is affected from bug 21464"

While doing all these tests I've gound that libgeos still has this bug 
and most of all, the diff proposed doesn't fix bug 21464, they are 2 
different bugs, so I've updated that here:

And submitted the other bug:

So bug 21464 is still there and my binutils patches need do be re-worded.

And please drop my pending patch:

I've submitted a reworded one:
