Subject: configure: Make missing docbook2man an error if man build requested
X-Git-Tag: v0.8.3~45
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b6143aa55eb8efa715d2511844790dd92cdaa483;p=thirdparty%2Fnftables.git

configure: Make missing docbook2man an error if man build requested

Previously, if man page build was enabled but no suitable docbook2man or
the like tool was found, build failed at a later stage with
undescriptive error message. Fail early and explicitly at configure
stage instead.
