Hi Niels,

Thanks for folding the fix in, I appreciate that.

Apologies for the confusion on the context. CLT is indeed a reference to
Apple's "Command Line Tools" package. As you're likely aware Apple offer
both Xcode (which is a full IDE) and the CLT package (which is more or
less the absolute minimum set of tools required to do development work
on macOS).

Both Xcode & the CLT package provide LLVM, which is where Apple has
shipped a stack checking addition which embeds the new symbol into most
binaries & libraries. If you'd prefer to reference the LLVM/Clang
version rather than the Xcode/CLT version, the string for that is
currently: Apple LLVM version 10.0.0 (clang-1000.10.25.5). That string
will change over time, but could safely be summarised as Apple LLVM
version 10+ or such.

A minor complication trying to describe the new feature in the patch is
that Apple have been trying to upstream the change to LLVM for quite
some time (https://reviews.llvm.org/D40864#1100905) but it hasn't yet
been merged there. Eventually though it seems likely that the feature
will be supported in both "Apple LLVM" & LLVM itself, at which point the
description I added to `symbols-test` will need updating; I'll do my
best to spot if/when that happens.

I think I've managed to add a fair dose of complication to the
explanation here but hopefully the context is somewhat clearer. Let me
know if not.
