Fixes #197278.

Also, remove the CLT requirement for pouring bottles. Many users use
this for the libraries, which don't need the CLT. We can add it back if
users report getting tripped up by this.

You'll want macosx#{macos_version} and darwin#{kernel_version}

Will do, thanks. Also, just remembered:

What about *-apple-macos*? I think that's a valid triple too. 🙃

[Bo98]

My upstream patch calls Triple.getOSTypeName which should already normalise that to macosx. Can double check with the built bottle to be sure.

Thanks!
