[OE-core] [PATCH 3/4] kern-tools: fix processing for no branch meta-data

[Trevor Woerner]

This patch does fix the raspberrypi issue, and it has been pushed, thankfully.

But I'm still seeing hard-coded filenames in /tmp that are messing up
the ability for more than one person to use a given build machine.
E.g.:

/tmp/patch.standard.arm-versatile-926ejs.queue
/tmp/patch.standard.mti-malta32.queue
/tmp/patch.standard.mti-malta64.queue
/tmp/patch.standard.preempt-rt.base.queue
/tmp/patch.standard.preempt-rt.queue
/tmp/patch.standard.queue
/tmp/patch.unused.queue

I think the malta ones are used for qemumips64, which is still failing
for this reason (multiple users)
