Q: Is there an assertion in anywhere in the build pipeline so that homebrew is installed and these expectations (such as /homebrew/bin/ld64.lld are available?

With #2884, macos_lld is a build configuration we opt in to in the release job, and we run brew install lld before that. Homebrew itself is always installed in the image.
Now that I think about it the /opt/homebrew/bin/ld64.lld requirement is precisely why this is actually failing – the homebrew binary paths are different on x86 and Apple Silicon, and since the release job is on x86 we'll need different paths here.

Figured out a way to not use an absolute path – glad there's a platform-independent option!
This appears to be needed for the clang driver to find LLD when using older clang versions.

=============
This (hopefully) fixes macOS CI release builds.
