The sstate cache mechanism currently has a blind spot: log messages shown
while a task first runs are not replayed when the task output comes back
from the cache. This is particularly true for warnings, which are
effectively hidden unless the task is rebuilt.

This bitbake series provides the needed support, storing each task's log
to a file that the openembedded-core series can later retrieve.
