build/siggen: Ensure a task signature file is generated for each task that is executed
Tracing down signature changes and dependencies is hard unless the complete task chain can be evaultated. Since we have the data available at task exeuction time, writing it to disk makes sense. This change is suboptimal internal knowledge stamp_internal() has leaks into make_stamp() and the concepts used by this code need revisiting but the change brings enough usability benefit to warrant its inclusion despite that. Addresses issue [YOCTO #1074] (Bitbake rev: 139b8a625818225c358a1b8363518d7ed6913188) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
