Okay, I'm trying to help someone with a NetBSD 9.1 machine at work.
Today's issue is one I had trying to build a kernel. We needed to do
this because that project has a few customziations in the system needed
to build the application layer, and more needed to run it.
He installed stock 9.1, but did not install any source; /usr/src and
/usr/xsrc did not exist. We then set up the customized source trees in
his homedir, which I will here call /home/abcxyz, under a directory
9.1. Thus, the path to kernel source, for example, was
/home/abcxyz/netbsd-9.1/usr/src/sys.
Then I copied in a kernel config (GEN91) into my ~/kconf/GEN91, from
back when I was working on that project. I then ran
% config -b ~/kbuild/GEN91 -s /home/abcxyz/netbsd-9.1/usr/src/sys ~/kconf/GEN91
This completed apparently normally, reporting the build directory and
telling me to remember to make depend. I then went to ~/kbuild/GEN91
and ran make depend && make. It failed fast - no more than a second or
two - with
make[1]: don't know how to make absvdi2.c. Stop
(full log below). I then moved /home/abcxyz/netbsd-9.1/usr/{src,xsrc}
to /usr/{src,xsrc}, chowned them -R to 0, destroyed ~/kbuild/GEN91, and
repeated, only this time I passed /usr/src/sys to config's -s flag.
This time the kernel built fine (at least apparently - we haven't tried
booting it yet, but I've built enough kernels to be confident there are
no obvious red flags in the log; it certainly did not fail a second or
two in with a cryptic message about absvdi2.c). Note in particular
that the source tree content was identical; only the path and ownership
differed.
Is this a bug? Or am I doing something wrong?

The logfile includes one line that's over 3300 characters long,
guaranteeing that it'd get mangled by email (soft limit 78 characters,
hard limit 998). So, I ran the logfile through bzip2 and then
base64-encoded the output. Here's the result:
