I see you set ARCHIVE_DIR, but I don' see you move or copy any files to 
this directory, am I missing something?

Also, do you want to name the tarball PF or BP, which deals with 
removing any multilib naming issues if the build it multilib.

Note BP = ${BPN}-${PV} so it removes the ${PR} if that is important 
(which it might be).
