    build: Fix srcdir != builddir from git
    
    Mimicing Colin's commit fb9b02e for E-D-S.
    
    We can't do (cd $(srcdir); ...) and inside reference $(top_srcdir)
    because that variable uses a *relative* path.  Thus we copy the
    approach from gnome-shell of explicitly using addprefix to append
    the source directory.
