Most of the messages are gone in -r325700 . But there was:

*** Creating the temporary root environment in /var/tmp/temproot
 *** /var/tmp/temproot ready for use
 *** Creating and populating directory structure in /var/tmp/temproot

[Creating objdir /usr/obj/usr/src/arm64.aarch64...]
[Creating objdir /usr/obj/usr/src/arm64.aarch64/etc...]
[Creating objdir /usr/obj/usr/src/arm64.aarch64/etc/sendmail...]

(No more objdir lines after that.)
