fix(?): some `extern` functions couldn't be found

[jjangga0214]

Hi, after adding sha1 to cargo, build fails for x86_64-unknown-linux-gnu-gcc.

I build in docker (for specific requirement). I guess there might be some system library dependencies that the docker image misses. If there's something like that, please let me know.

Thanks!

[tarcieri]

This is a linking error of the sort you wouldn't normally expect from pure Rust code, especially on a target like x86_64-unknown-linux-gnu. I'm guessing it's some sort of environmental issue.

Can you post a full reproduction, including the Cargo project and ideally the Dockerfile as well?

@tarcieri You're right. I thought the only change I made was adding sha1, but actually an unexpected change was committed without my knowing. Thanks a lot.
