Some versions of Android do not implement memfd_create() wrapper in their libc implementation, leading to build failures ([0]). On the other hand, memfd_create() is available as a syscall on quite old kernels (3.17+, while bpf() syscall itself is available since 3.18+), so it is ok to assume that syscall availability and call into it with syscall() helper to avoid Android-specific workarounds. Validated in libbpf-bootstrap's CI ([1]).
