When building either tools/bpf/bpftool, or tools/testing/selftests/hid,
(the same Makefile is used for these), clang generates many instances of
a warning that is useless here:
"clang: warning: -lLLVM-17: 'linker' input unused"
Silence this in both locations, by disabling that warning when building
with clang.
