Build of v3.9.0 fails with --feature=rkyv

[blp]

v3.9.0 uses the rend feature in rkyv that rkyv only implements conditionally on other features. This breaks the build if you specify the rkyv feature. This is true in v3.9.0 but not in v3.8.0:

[blp@sigxcpu rust-ordered-float]$ git checkout v3.8.0
HEAD is now at 651ead6 Version 3.8.0
[blp@sigxcpu rust-ordered-float]$ cargo build --features=rkyv
    Finished dev [unoptimized + debuginfo] target(s) in 0.01s
[blp@sigxcpu rust-ordered-float]$ git checkout v3.9.0
Previous HEAD position was 651ead6 Version 3.8.0
HEAD is now at 2650e6e Version 3.9.0
[blp@sigxcpu rust-ordered-float]$ cargo build --features=rkyv
