Since generated man pages are also included, we can't
guarantee proper timestamps. This should fix issues that trigger doc
building when it isn't needed.

Run `make doc` in the build directory after editing the asciidoc to
regenerate the manpages. Changes to asciidoc source and generated man
pages will need to be commited together.
