While archiver inherited, we edit a recipe (such as gzip) to
insert four tasks between do_patch and do_unpack:
...
addtask test1 after do_unpack before do_patch
addtask test2 after do_unpack before do_test1
addtask test3 after do_test2 before do_test1
addtask test4 after do_test2 before do_test1
...

While building the recipe, the archiver will
missing these four task in do_unpack_and_patch.
Because it is hardcoded to execute do_unpach and do_patch,
did not consider the probable tasks between them.
