I don't know what is happening here for you. The 'build.sh' script is 
called by the 'dpkg.bbclass' like this:

     sudo -E chroot ${BUILDCHROOT_DIR} /build.sh ${PP}/${PPS}

You can look at what those variables are by either inspecting the all 
environments "bitbake -e ...| grep -E '^(PP|PPS)'" or looking at the 
generated shell scripts of this task: 
/mnt/elbe/Isar/isar/build/tmp/work/lynx-armhf/imx-kobs-5.5-r0/temp/run.do_build

For me with the example-hello recipe it looks like this:

   PP="/home/builder/example-hello"
   PPS="example-hello-0.2-86cc719"

Good luck,
Claudius
