configure.ac : disable doc by default and check for asciidoc

This is a complaint that has been reported many many times. By default, docs
are enabled and there is no check for asciidoc, so anyone building from git
will see their build fail.

We cannot do a strict check for asciidoc because released source tarballs
have man pages already built, and it should be possible to install them
without having asciidoc.

This patch attempts to improve the situation in two ways :
1) disable doc by default
2) print a warning if docs are enabled but asciidoc is not installed
