We are having more and more schema files.

Commit 8b6b80218b01 ("dt-bindings: Fix command line length limit
calling dt-mk-schema") fixed the 'Argument list too long' error of
the schema checks, but the same error happens while cleaning too.

'make clean' after 'make dt_binding_check' fails as follows:

  $ make dt_binding_check
    [ snip ]
  $ make clean
  make[2]: execvp: /bin/sh: Argument list too long
  make[2]: *** [scripts/Makefile.clean:52: __clean] Error 127
  make[1]: *** [scripts/Makefile.clean:66: Documentation/devicetree/bindings] Error 2
  make: *** [Makefile:1763: _clean_Documentation] Error 2

'make dt_binding_check' generates so many .example.dts, .dt.yaml files,
which are passed to the 'rm' command when you run 'make clean'.

I added a small hack to use the 'find' command to clean up most of the
build artifacts before they are processed by scripts/Makefile.clean

JFYI, we are running into the "Argument list too long" simply by trying to
clean an out-of-tree module (with lots of artifacts though), as below.
Seems to be happening on vanilla (v6.4-rc6-199-gb73056e9f82ebd) too.
Just in case there are any known hacks (or similar reports), please let us know.

$ make -C /data/linux-src M=my_module clean

make: Entering directory '/data/linux-src'
make -f ./scripts/Makefile.clean obj=my_module
set -e;  echo '  CLEAN   my_module';  rm -rf [~1k filenames / 200k char]
make[1]: /bin/sh: Argument list too long
make[1]: *** [scripts/Makefile.clean:45: __clean] Error 127

I sumitted a patch
https://patchwork.kernel.org/project/linux-kbuild/patch/20230617153025.1653851-1-masahiroy@kernel.org/

I do not know whether it will solve your problem or not.

Your module Makefile has ~1k files to remove.

It may still exceed ARG_MAX limit.
