Set commit information environment variables when building tools This fixes #107094. ~I'm trying to add a regression test for this issue.~ **Update**: I've added a test and a new test header `needs-git-hash` which makes sure it doesn't run when commit hashes are ignored (`bootstrap`'s `ignore-git` option).
This directory contains some source code for the Rust project, including:
- The bootstrapping build system
- Various submodules for tools, like cargo, tidy, etc.
For more information on how various parts of the compiler work, see the rustc dev guide.
