build-sys: generate all man pages for distribution tarball

Now "make dist" and "make distcheck" follows autoconf. It means that
disabled tools or tools that cannot compile are ignored, and man-pages
for these tools are not generated. This is a problem for people
without asciidoctor (adoc -> man generator).
