FYI a check-old (with MAKEOBJDIRPREFIX="/usr/obj/cortexA53_clang/arm64.aarch64"
in use) got me a:

[Creating objdir /usr/obj/cortexA53_clang/arm64.aarch64/usr/src/arm64.aarch64...]

(Just the one objdir line.)

/usr/obj/cortexA53_clang/ did not exist when check-old
was started.

So, the activity does track MAKEOBJDIRPREFIX when it
is in use.
