some plugins are installed into libdir/opensaf but we were making a copy
into libdir as well, this patch changes that so the packaged files are
appearing only once
create_empty_library should be using cross compiler with linker flags,
existig code in this area is not cross compile friendly
skip dev-so QA test since some .so are stubs which are packages in PN
