The rust-1.57 variable should probably be made private or hidden now.

Also, unless we rebuild all crates with rust-1.58, it seems to me like
we won't be addressing the problem, as the CVE touches the
'remove_dir_all' procedure part of the standard library of Rust (and we
all know Rust likes to build things statically).

Am I missing something?

Thanks,

Maxim
