Hmmm I'm not sure about that one, I pretty much remember seeing failing
arm64 builds when mrproper and prepare were missing.

I would argue that someone starting "make defconfig" does expect the
config to be dropped, hence mrproper to be called as well.

What specific issue did you face with it ? Maybe we can restrict it to
only a few cases ?
