b0c3d7133f:

/nvmedata/autobuild/instance-26/output-1/host/opt/ext-toolchain/bin/../lib/gcc/sparc-buildroot-linux-uclibc/10.3.0/../../../../sparc-buildroot-linux-uclibc/bin/ld: /nvmedata/autobuild/instance-26/output-1/build/bpftool-v6.7.0/src/libbpf/libbpf.a(libbpf.o): in function `bpf_program__attach_kprobe_opts':
libbpf.c:(.text+0xff88): undefined reference to `__sync_fetch_and_add_4'
