You're right, that was a too quick fix. 

Here you go with the /dev/null redirect.

Subject: [PATCH] gen-version.sh: check if git is available before trying to
 call it

Some people may clone the cgit repository and compile within a sandbox
or on another machine where git is not necessarily installed. When it
happens, cgit is getting compiled with an empty version number.

This commit fixes this.
