Linking Error

[obraunsdorf]

Hi,
I tried installing the detector as described in the Readme using cargo install --path . within a docker container running the rust:latest image.
Unfortunately the following error occurs.

error: linking with `cc` failed: exit code: 1

Thx @obraunsdorf. I found that component llvm-tools-preview is a requirement to fix this issue. I've added that in README.md in PR #9. Could you check if it can work after running "rustup component add llvm-tools-preview" under dir "rust-lock-bug-detector"?

[obraunsdorf]

That solved it, thank you :)
