doc build error: mirrors-docbook-country-index-without-period variable not declared

[Joshua Tinnin]

This has been posted before, and there has been at least one PR filed,
but thought I'd add that this problem is ongoing and affects me as well.
The error is pretty much the same as everyone else, from my last build
attempt:
