[yocto] busybox: adding task to run before do_configure

[Måns Zigher]

Hi,

Thanks for your answer. So this is a simplified implementation so you are
right. I have based my implementation on a class used for kernel you can
find the original implementation here
https://github.com/resin-os/meta-resin/blob/master/meta-resin-common/classes/kernel-resin.bbclass.
I am not sure I understand it fully but the error is not reproducible
there. You can modify the config in two ways you can define areas to modify
in the config but you can also define a new config to base it on and I
thought that the deptasks was need to make sure that configured is called
again. But maybe you are right there is no reason for it. But I am
still curious how it can affect the staging part of install task since it
is not affecting the kernel and I am not doing anything in the tasks.
