Yeah, noticed it locally too. We'll need to add faccessat2 to list of allowed syscalls. Somehow scanelf just works for me and fails only when ran under emerge. I wonder why.

Filed https://github.com/seccomp/libseccomp/issues/314 to add `faccessat2` to libseccomp syscall list.

Unfortunately libseccomp does not yet provide syscall definition for faccessat2. Define it locally.
