[PATCH] Documentation: fix man page dependency on asciidoc.conf

When building manual pages, the source text is transformed to XML with
AsciiDoc before the man pages are generated from the XML with xmlto.

Fix the dependency in the Makefile so that the XML files are rebuilt
when asciidoc.conf changes and not just the manual pages from unchanged
XML.
