Oh right. I guess it works fine when having built 3.7 and then building
3.8, since you'd look in the new location first and only fall back to
the old location if missing. However, if you then switch back to 3.7 to
test something, I guess that doesn't work so well.

I tend to always build the dtbs target, so I wasn't affected by this.
And, often run "git clean -f -d -x" too.

Grant, what's your call on this issue; should I/you look into ways to
clean the files better, or do you want to revert this?
