Building lld using the lld = true option fails on latest master (3130203). Here is my config.toml:

# Includes one of the default files in src/bootstrap/defaults
profile = "library"
changelog-seen = 2

[llvm]
download-ci-llvm = "if-available"
ccache = "/bin/ccache"
ninja = true

# [build]
# target = ["x86_64-unknown-uefi"]

[rust]
lld = true
incremental = true
deny-warnings = false

[target.x86_64-unknown-uefi]
linker = "rust-lld"

I am getting the following error output:

I was able to build fine until rebasing to master, so I think this might be caused due to llvm update that recently took place.

I believe we don't currently support building LLD when download-ci-llvm is used.

Yeah, it builds when using download-ci-llvm = false. Guess it was just luck that it built fine before rebase

The new `download-ci-llvm` configuration option dosn't work with `lld =
true` (see rust-lang#100853). The Fuchsia walkthrough should recommend setting it
to `false`.
