the "fix" here was a red-herring - it uses a non-Debian version of
the libc crate, which is lacking y2038 patches, and thus doesn't expose
the issue.

the real root cause is that the rustix and libc crates don't agree on
the targets that require y2038 compat/have 64-bit timestamps.

I've verified a fix on powerpc that should also unbreak other targets,
and will upload that shortly.
