commit 40e7eecb7efeeb9af59206d7a9c82ac55adf5279
Author: Noel Grandin <noel at peralex.com>
Date:   Thu Nov 20 16:02:57 2014 +0200

    add sanity checking to --with-iwyu
    
    add some error checking so developers like me don't pass an empty
    --with-iwyu option and get weird compile time error messages.
