    build-sys: really make gtk-doc optional & some portability fixes
    
    The failing check caused autogen.sh to die mysteriously due to `set -e`
    and the unquoted `test -z $VAR`.
    
    Also, some syntax fixes to make it work with /bin/sh, which most other
    autogen.sh's use.
    
    [zj: implemented simplification suggested by Peters Simon
     and fixed the case where gtkdocize was available but is not anymore.]
