[bitbake-devel] [PATCH 1/4] siggen: ensure nostamp tasks force dependent tasks to re-execute

If a nostamp task is depended on by a non-nostamp task, then we want the
signature of that task to change such that it re-executes afterwards.
This is an unusual situation, but we want this to work in OE in
externalsrc.bbclass so that compilation happens every time it is
requested.
