Do you mind trying to see if it's possible to detect that plain `make`
is being run from samples/bpf subdirectory, and if that's the case,
just running something like `make M=samples/bpf -C ../../`? If that's
not too hard, it would be a nice touch to still have it working old
(and intuitive) way, IMO.
