When building rust-1.84.0 from the source tarball on Linux I'm seeing the following in a backtrace:

thread 'main' panicked at src/utils/tarball.rs:397:21: generated a symlink in a tarball: /builddir/build/BUILD/rustc-1.84.0-src/build/tmp/tarball/rustc/x86_64-unknown-linux-gnu/rustc-1.84.0-x86_64-unknown-linux-gnu/rustc/lib/rustlib/x86_64-unknown-linux-gnu/bin/rust-objcopy

My config.toml has the following:

profile = "dist" [llvm] link-shared = true download-ci-llvm = false [build] target = [ "x86_64-unknown-linux-gnu", "i686-unknown-linux-gnu", ] cargo = "/usr/bin/cargo" rustc = "/usr/bin/rustc" rustfmt = "/usr/bin/rustfmt" locked-deps = true vendor = true tools = ["cargo", "clippy", "rustdoc", "rustfmt"] sanitizers = true profiler = true docs = false [install] prefix = "/usr" [rust] codegen-units-std = 1 debuginfo-level = 1 debuginfo-level-std = 2 channel = "stable" description = "" rpath = false frame-pointers = true lld = false use-lld = "external" llvm-bitcode-linker = false deny-warnings = false backtrace-on-ice = true remap-debuginfo = false jemalloc = true # codegen-tests depend on LLVM utils (FileCheck) we don't provide codegen-tests = false 

Looking at another issue I tried llvm-tools = false and hit a different issue:

src.symlink_metadata() failed with No such file or directory (os error 2) ("src = /builddir/build/BUILD/rustc-1.84.0-src/build/x86_64-unknown-linux-gnu/stage2/lib/rustlib/x86_64-unknown-linux-gnu/bin/llvm-objcopy")

I'm inclined to just patch out the test for the symlink in the tarfile for now as that appears to be only there because of windows but this seems like a problem regardless.
