libbpf: Fix sym->st_value print on 32-bit arches
The st_value field is a 64-bit value and causing this error on 32-bit arches: In file included from libbpf.c:52: libbpf.c: In function 'bpf_program__record_reloc': libbpf_internal.h:59:22: error: format '%lu' expects argument of type 'long unsigned int', but argument 3 has type 'Elf64_Addr' {aka 'const long long unsigned int'} [-Werror=format=] Fix it with (__u64) cast. Fixes: 1f8e2bcb2cd5 ("libbpf: Refactor relocation handling") Reported-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org>
