Subject: build: Require scdoc if building man pages
X-Git-Tag: v33~44
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=aa125fbc4a46fb2428aee8e14a2f484661b799e6;p=thirdparty%2Fkmod.git

build: Require scdoc if building man pages

Instead of creating invalid man pages, make sure the configure step
fails if scdoc is not available.
