denoland/deno#1495 (comment) points to this needing glibc support. cargo-deadlinks should instead target x86_64-unknown-linux-musl, which doesn't require glibc.

It turns out this is non-trivial.

• libmusl with static OpenSSL? cross-rs/cross#21

Yay, the openssl issue was magically fixed by switching from reqwest to ureq 🎉
