Add the configure options specified in $(TAGS) that equal 1 as tags on
the Sphinx command line using the -t option. The tags may be used to
conditionally include documentation using the Sphinx "only" directive
[1].
As an example, indicate in the documentation whether the Xapian field
processor is likely to be available (assuming the notmuch binary was
built in the same environment as the documentation).

Just an idea, not sure if it makes sense.
