Description
Command
I tried this with Rust 1.66.0, simplified from my build for Fedora:
$ ./configure --local-rust-root=/usr
$ ./x test bootstrapI expected to see this happen: passing tests
Instead, this happened: 20 builder::tests::... failures, all of this sort:
---- builder::tests::alias_and_path_for_library stdout ----
failed to execute command: "/builddir/build/BUILD/rustc-1.66.0-src/build/x86_64-unknown-linux-gnu/stage0/bin/rustc" "--target" "x86_64-unknown-linux-gnu" "--print" "target-libdir"
error: No such file or directory (os error 2)
thread 'main' panicked at 'status code: 1', lib.rs:1654:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
My stage0 should be using /usr/bin/rustc.
Version it worked on
It most recently worked on: Rust 1.65.0
Version with regression
rustc-1.66.0-src/version:
1.66.0 (69f9c33d7 2022-12-12)
I bisected this to #98483, commit 55c040e, which stopped using CARGO and RUSTC environment variables when building a Config.
