The signature stuff was one problem; there is another, more trivial (but
probably more difficult) one:

Adding a task like

| addtask do_rm_old_work before do_unpack

causes stampfile dependencies for the shared gcc like

gcc.do_unpack ->  gcc-initial.do_rm_old_work
gcc.do_unpack ->  gcc-intermediate.do_rm_old_work

E.g. the earlier 'do_rm_old_work' stamps are recipe dependent but the
later 'do_unpack' are shared between recipes. Bitbake reexecutes do_unpack
when the corresponding do_rm_old_work is newer which is causing the seen
errors.

For now, I will declare the task as 'before do_compile'.
