[Buildroot] [PATCH] czmq: disable asciidoc documentation generation

[Arnout Vandecappelle (Essensium/Mind)]

From: "Arnout Vandecappelle (Essensium/Mind)" <arnout at mind.be>

czmq uses asciidoc for its documentation. asciidoc uses python and import
the unicodedata module, which is not in host-python. So disable asciidoc
entirely.

This doesn't get hit by the autobuilders because they don't have asciidoc
installed in their chroot.
