This is just a documentation patch right? Nothing actually changes with
the build. The only possible thing that we would potentially have to
deal with is

(1) people noticing the doc change and complaining that they
still need to use binutils-2.21 for some reason -- but they can't
currently build an x86 kernel without patches anyway, so...

(2) people noticing the doc change and suggesting moving to 2.26 or some
later version instead of 2.23.
