Describe the bug

binutils is currently 2.31.1 in nixpkgs master. It was released in July 2018.

2.33.1 was released in October 2019. It contains a few improvements and may also contains fix for some vulnerabilities: #63061

Is there a reason to keep the old version in nixpkgs, other than a lack of manpower?

I'd be happy to do this work, but I just want to be sure that I was not starting a long, difficult and redundant work. I already tried a "naive" bump of the version and sha256 but it does not work, mostly because most of the patchs are not valid anymore.
