libbpf: Fix build on ppc64le architecture
On ppc64le we get the following warning:
In file included from btf_dump.c:16:0:
btf_dump.c: In function ‘btf_dump_emit_struct_def’:
../include/linux/kernel.h:20:17: error: comparison of distinct pointer types lacks a cast [-Werror]
(void) (&_max1 == &_max2); \
^
btf_dump.c:882:11: note: in expansion of macro ‘max’
m_sz = max(0LL, btf__resolve_size(d->btf, m->type));
^~~
Fix by explicitly casting to __s64, which is a return type from
btf__resolve_size().
Fixes: 702eddc77a90 ("libbpf: Handle GCC built-in types for Arm NEON")
