Ilya Leoshkevich 0f0e5f5bd5 bpf: iterators: Split iterators.lskel.h into little- and big- endian versions 
iterators.lskel.h is little-endian, therefore bpf iterator is currently
broken on big-endian systems. Introduce a big-endian version and add
instructions regarding its generation. Unfortunately bpftool's
cross-endianness capabilities are limited to BTF right now, so the
procedure requires access to a big-endian machine or a configured
emulator.

WARNING:
If you change "iterators.bpf.c" do "make -j" in this directory to
rebuild "iterators.lskel-little-endian.h". Then, on a big-endian
machine, do "make -j big" in this directory to rebuild
"iterators.lskel-big-endian.h". Commit both resulting headers.
Make sure to have clang 10 installed.
