I have 8.6.9-3 installed (it is part of Debian testing/unstable now),
and confirmed that:

diff --git a/Documentation/asciidoc.conf b/Documentation/asciidoc.conf
index 2c16c53..10c777e 100644
--- a/Documentation/asciidoc.conf
+++ b/Documentation/asciidoc.conf

 ifdef::backend-docbook[]
 [linkgit-inlinemacro]

drops the "last-updated" footer.

But note that this only affects the generated HTML. The manpages still
get the date in their footer. But this isn't an asciidoc-ism at all;
it's added by docbook when converting the xml to roff. I'm sure there is
a way to tweak that, too, but looking at docbook gives me nightmares.
