If we have a recipe which has the BBCLASSEXTEND = "native" set and if we
want to add a task just for the <recipe>-native alone. I thought, I
could check the ${PN} and add the task dynamically. Since the above
method is flawed. I followed a simpler and straight forward approach
without tweaking the bitbake's internal variable. (Hope this helps
someone)

        BBCLASSEXTEND = "native"
        addtask some_task after do_compile before do_install
        
        python __anonymous () {
            pn = d.getVar('PN', True)
            if not pn.endswith("native"):
                d.setVarFlag('do_some_task', 'noexec', '1')
        }
