Subject: [PATCH bpf 0/2] samples: bpf: fix build issues with Clang/LLVM

Samples, at least XDP ones, can be built only with the compiler used
to build the kernel itself.
However, XDP sample infra introduced in Aug'21 was probably tested
with GCC/Binutils only as it's not really compilable for now with
Clang/LLVM.
These two are trivial fixes addressing this.

Alexander Lobakin (2):
  samples: bpf: fix xdp_sample_user.o linking with Clang
  samples: bpf: fix 'unknown warning group' build warning on Clang
