[Daiki Ueno <dueno src gnome org>]

commit 86fdbc3e7cd3a5e8d03d94d30056740d3a805001
Author: Daiki Ueno <ueno unixuser org>

    build: make sure to define $datarootdir in generated scripts
    
    Some of automake standard directory variables are expanded using
    "${datarootdir}", which must be available at run-time.  Define it
    at the beginning of the script templates.
