Interesting...

I have no idea why that is there, but it does look strange, I agree.

In this particular case however the binutils are not to blame as the
config.sub file (and the config.guess file) are actually taken from a
different project:

  https://savannah.gnu.org/projects/config/

We just use copies of the files from that project.  We synchronize the
files occasionally, usually just before an official release.

Good, I shall now stop panicking. :-)

If you feel motivated, please do take this issue up with the config
project.  If it caused problems for you then it is likely to cause
problems for other people in the future.  So fixing it, or at least
adding a comment explaining the reasoning to the config.sub file,
would be a good thing.
