[PATCH 3/4] Docs: Makefile tweaks for asciidoc templates

[Jonathan Corbet]

This is a hatchet job, but it's something to start with.  Generalize some
of the string manipulation to not assume that templates have a ".tmpl"
suffix, and add rules to translate asciidoc templates to HTML.  Nothing for
any other output formats at this point.
