Hi Masahiro,
Sorry about the late report, commit
24507871c3c6ae4f6b460b016da7ff434cd34149 ("kbuild: create a list of all
built DTB files") is breaking the build when we are doing a rsync of the
Linux sources into a build directory, which is how buildroot works when
doing a source directory override.
This does not happen when doing a build from the git directory
containing the sources, and I cannot find a missing $(obj) reference, so
I am left wondering what I am missing here. The build error looks like this:
cat: arch/arm64/boot/dts/actions/dtbs-list: No such file or directory
host-make[3]: *** [scripts/Makefile.build:423:
arch/arm64/boot/dts/dtbs-list] Error 1
host-make[3]: *** Deleting file 'arch/arm64/boot/dts/dtbs-list'
host-make[2]: *** [Makefile:1394: dtbs] Error 2
host-make[2]: *** Waiting for unfinished jobs....
running with verbose, we can see the rule not generating an empty file
at all:

Buildroot builds its own GNU Make version 4.4.1.
Any clues what might be going on? My defconfig is such that only
CONFIG_ARCH_BRCMSTB is enabled, and there are essentially no .dtbs file
that will be generated.
Thanks!

Adding Markus since he helped me with a similar issue before that showed
up entirely differently around last year. I had an alias that basically
does the following to build a kernel using buildroot:
make DESTDIR=/path/to/tftp/$KVER linux-reconfigure all install -j48
down the road in buildroot this ends-up building the kernel. The first
time I had a problem this is what happened:
ff944844@stbirv-lnx-2:/local/users/fainelli/buildroot/output/arm64$ make V=1
test -d images || mkdir images
test -r images/rootfs.cpio || touch images/rootfs.cpio

we would basically end-up in an endless syncconfig make recipe and there
would be no forward progress. Markus had done a great job at identifying
that the problem, and he provided the following:
* The problem DOES happen with GNU make 4.4.1 and Linux 5.4 (and,
presumably, older kernels)
* The problem does NOT happen with GNU make 4.4 or older, irrespective
of the kernel version
* The problem also does NOT happen with Linux 5.15 (and, presumably
newer), irrespective of the GNU make version
So, this would seem to be some feature / change that was introduced in
GNU make that the kernel build system subsequently accounted for. Or
it could be independent changes where the kernel build system changed
first and GNU make changed later; 4.4.1 was only tagged on February
26, 2023.
And eventually he tracked it down to two commit of you, one in GNU Make:
https://git.savannah.gnu.org/cgit/make.git/commit/?id=a275f4e9ab14
and an innocent Linux change that ended up "fixing" the issue:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=77342a02ff6e
Sure enough, the machine on which I had the issue I reported to you with
the dtbs-list being empty still used the old alias for building a kernel.
I would like to give you a minimal reproducer, because it seems like
there is a genuine issue that just shows up in unexpected ways here. The
key thing is really specifying a DESTDIR variable on the make command
line of buildroot, which eventually makes it to Linux's build system and
breaks in unexpected ways.
Thanks!
