revert the last change to this Makefile which removed the rules to build

app_apt.  These rules *are* needed beacause this module uses libtonezone,
so it needs this information from autoconf in case it is located in a
non-standard location.  Also, without it, app_rpt.so would not be linked
with libtonezone at all.
