x.py build fails with download-ci-llvm = true #80086
Description
I just started running into this recently - maybe llvm-dwp stopped being packaged recently? I think the fix is just to make it optional in bootstrap.
$ x.py build
Copying stage0 rustc from stage0 (x86_64-unknown-linux-gnu -> x86_64-unknown-linux-gnu / x86_64-unknown-linux-gnu)
Assembling stage1 compiler (x86_64-unknown-linux-gnu)

A workaround is touch build/x86_64-unknown-linux-gnu/ci-llvm/bin/llvm-dwp.

This is likely a regression from #77117, cc @davidtwco

Hitting this despite doing
rm -r buildand updating to latest. The workaround works though.jyn514 commentedon Dec 17, 2020
Yup, this still fails for me after b32e6e6.

Oh, we forgot to bump the stamp file so we're not downloading a fresh copy.

https://github.com/rust-lang/rust/blob/master/src/bootstrap/download-ci-llvm-stamp should be bumped in a PR to fix this.
