I'll use that definition line for the below.

I'll ignore there that that is skipping too much
and just show what happens for the 2nd buildkernel
of 2 in a row when I use that exact line for both
make runs.
First counts of the "is newer than" lines, counting
separate program names separately:
# cat =

64-nodbg-clang-amd64-host-2023-02-23:16:15:18 | grep "is newer than the =

Thousands of rebuilt things based on:
. . ./tmp/legacy/usr/sbin/realpath
. . ./tmp/legacy/usr/sbin/ln
It appears that buildkernel does not use an OBJTOP definition
that references:
/usr/obj/BUILDs/main-amd64-nodbg-clang/usr/main-src/amd64.amd64
in my context.
For reference of Build lines paired with a few of those "is newer
than" lines:
First realpath:
