I'd expect to just prepend the directory path for the rules from subdirs
Perhaps with

    echo "syntax: glob" > .hgignore
    for ignore in `find $(srcdir) -name .gitignore
    do
       dir=`dirname $ignore`
       for rule in `cat $ignore` 
       do
          echo "$dir/$rule" >> .hgignore
       done
    done
