bpftool uses its own local copy of libbpf so add
BR2_PACKAGE_BPFTOOL_ARCH_SUPPORTS to avoid the following build failure
on ARM:
btf.c: In function 'btf_type_by_id':
btf.c:461:14: warning: comparison between signed and unsigned integer expressions [-Wsign-compare]
if (type_id < btf->start_id)
^
bpf.c:62:4: error: #error __NR_bpf not defined. libbpf does not support your arch.
# error __NR_bpf not defined. libbpf does not support your arch.
^
