-> Rebuilds everything.

This doesn't occur before the offending commit. So it only happens
when specifying extra environment variables on the command line.

I suspect if you also provide the CONFIG_DEBUG_SECTION_MISMATCH=y on the
dtbs line, everything will work properly.

Yay, it works! :)

The problem is that dtbs line executes a prepare, which I guess rebuilds
the bounds stuff.  So, the dtbs target results in it being rebuilt without
the section mismatch, and then you re-execute a make with it, causing
the bounds stuff to be rebuilt again.

Yep. Not very intuitive to require passing section mismatch debug
flags to DTB rebuilding but whatever, it's not so bad I can't live with
it.

Still, the dependency on the 'prepare' target is superfluous, if the
only requirement is that $(KERNELRELEASE) be set properly.

So, I've lost track of where things stand on this issue. What is the
current proposed fix? Make dtbs depend on 'scripts' and dtbs_install
depend on 'prepare scripts'? Or is there a better way to make sure
KERNELRELEASE is set for the dtbs_install target?
