Don't try to build manpages if asciidoc is missing

Browse Source 
Commit f9157fd91d changed the rules for
the documentation, so make always tried to build it and failed if
asciidoc was missing since that commit.

Now configure tests whether asciidoc is available and builds the
documentation conditionally. It also reports that to the user.
