Our manual does not use external filters in asciidoc, so we are happy
with just looking for resources from our source tree.
However, other documents (like ones in br2-external) may use such
filters, to generate diagrams, graphs...
External filters generate their output files in the output directory, so
we must also look for resources in there.
Note: external filters in asccidoc are used thus:
["filter-name"]

Text to be rendered

In the future, our own manual may even make use of filters to include
some of the graphs we generate, to store in the documentation.
