This is uncovering a very difficult-to-debug build failure with NVIDIA DKMS:
with CONFIG_UNWINDER_ORC=y, out-of-tree modules hit this rule in
scripts/Makefile.build:

$(obj)/%.o: $(src)/%.c $(recordmcount_source) $(objtool_dep) FORCE

and fail (here, at least) to build tools/objtool/objtool (note: I do have
libelf-dev installed)

After editing dkms.conf to do `make --debug=a -j1`, I see make output:

 Considering target file
'/var/lib/dkms/nvidia-current/387.34/build/nvidia/nv-gpu-numa.o'.
  File '/var/lib/dkms/nvidia-current/387.34/build/nvidia/nv-gpu-numa.o'
does not exist.
  Looking for an implicit rule for
'/var/lib/dkms/nvidia-current/387.34/build/nvidia/nv-gpu-numa.o'.
  [...]
  Trying rule prerequisite 'tools/objtool/objtool'.
  Looking for a rule with intermediate file 'tools/objtool/objtool'.
   Avoiding implicit rule recursion.

then silently fail to build objtool, silently fail to build all the .o files,
then continue until ld finally errors out trying to link nonexistent object
files.

If things look alright to you, and objtool is known to work with out-of-tree
modules, and the Debian packaging just needs to be adjusted, please ignore;
I figured I'd send this anyway because it was such a pain to debug.

Thanks,

Ivan
