Bootstrap fails "No such file" for llvm-objcopy

[ehuss]

Recently, build of rustc is failing with:

src.symlink_metadata() failed with No such file or directory (os error 2) ("src = /rust/build/aarch64-unknown-linux-gnu/stage1/lib/rustlib/aarch64-unknown-linux-gnu/bin/llvm-objcopy")

Steps:

1. git clone https://github.com/rust-lang/rust.git
2. cd rust
3. ./x.py build

Meta

Currently on d4822c2

Tested on aarch64-unknown-linux-gnu and x86_64-unknown-linux-gnu

cc @jieyouxu (I think you did some work related to this very recently, if I am not mistaken)

@ehuss does #132720 fix it?

(That PR is in the queue, hasn't landed yet)

Maybe duplicate of #132719?

[jieyouxu]

#132719 is

src.symlink_metadata() failed with No such file or directory (os error 2) ("src = /home/runner/work/rustc_codegen_cranelift/rustc_codegen_cranelift/rust/build/x86_64-unknown-linux-gnu/stage1/lib/rustlib/x86_64-unknown-linux-gnu/bin/llvm-objcopy")

so yeah I'm fairly certain this is the same problem, i.e.

Shipping llvm-strip w/ a symlink breaks when bootstrap compiler doesn't contain any LLVM tools

Leaving this issue open for the time being in case ehuss is running into something different, but I'm fairly sure it's the same problem.

Yes, I verified that this is fixed by #132720, and that this was introduced by #131405.

Thanks, closing as a duplicate of #132719.
