[PATCH v2 0/5] doc: asciidoc cleanups

This patch series is an attempt to cleanup the Makefile of the documentation.

It's quie different from v1 mainly because now the .DELETE_ON_ERROR approach is being used as Aevar suggested, however it tries to do the same thing.

It does not enable asciidoctor direct man page creation, that's in a separate patch.

Felipe Contreras (5):
  doc: refactor common asciidoc dependencies
  doc: improve asciidoc dependencies
  doc: remove unnecessary rm instances
  doc: simplify Makefile using .DELETE_ON_ERROR
  doc: avoid using rm directly
