The reason I did it in db10fc6c09 is because both asciidoctor and
asciidoc should deal with temporary files by themselves (like gcc). If
you interrupt the build nothing gets generated.

However, other scripts like build-docdep.perl would indeed generate
partial output.

In my opinion it's the scripts themselves that should be fixed, and not
the Makefile, *if* we care about this at all.
