OK, I will add the usual text saying that the variable can be nil if the
information is not available.

What sort of error? It seems to work for me (not that I actually went all the
way and sent the email).
I had to back out the recent IDNA changes, as they broke report-emacs-bug --
perhaps that is what you noticed?

Consistency and simplicity. Consistency, because we should treat
emacs-build-system consistently with other primitives like process-attributes
and memory-info that return nil when the information is not available.
Simplicity, because it's simpler for code to test for nil than for some reserved
string like "unknown"; you can see examples of this in the most recent patch I
proposed. Besides, we shouldn't prevent Emacs from working correctly on a
machine whose host name really is "unknown".
