<pre>
    The buildabot for lld-x86_64-win-release checks out and attempts to build the latest release 18.x.  It shows an unexpected failure of the test lld :: wasm/signature-mismatch.s.  

This is demonstrated here: https://lab.llvm.org/buildbot/#/builders/153/builds/437

The problem is that a commit made on Jan 21 made the test try to use the command "ar", which is non-existent on windows.  

On Jan 24, commit https://github.com/llvm/llvm-project/commit/d8a34c25bcfe67243b4347e169a2a57a6da95321 was made, which addresses this problem, by changing the command to llvm-ar.

That commit exists in the main branch, but it does not exist in the release/18.x branch.  Prior release branches do not attempt to use an "ar" command.

Should that commit be merged into the release/18.x branch?
