[jhbuild] substitute ${exec_prefix} in autogen.sh/configure commands

[Frederic Peters <fpeters src gnome org>]

commit 4eb9a9ffcb1ab4b81cdab9089435b9043a519daf
Author: Frederic Peters <fpeters 0d be>
Date:   Sun Apr 26 13:07:10 2009 +0200

    substitute ${exec_prefix} in autogen.sh/configure commands
    
    If there is no --exec-prefix in the constructed autogen command, we
    can safely assume it will be the same as {prefix} and substitute it
    right at the moment, so the printed command can be copy/pasted
    afterwards.  (GNOME #580272)
