Few files in libbpf are using bzero() function (defined in strings.h header),
but
don't include corresponding header. When libbpf is added as a dependency to
pahole,
this undeterministically causes warnings on some machines:
bpf.c:225:2: warning: implicit declaration of function ‘bzero’
[-Wimplicit-function-declaration]
bzero(&attr, sizeof(attr));
