As per the bottom of the compiler output.

I'm currently working on getting Apple Silicon bottles built over on osx-cross/avr, so people running Sonoma and higher won't need to wait for Brew to compile the toolchains locally anymore.

Once that's finished I'll do the same for the ARM tap, and hopefully will be able to figure this out.

osx-cross/homebrew-arm#60

Just wanted to add a note that this appears to be an issue with the macOS 14.4 SDK; I just reinstalled XCode 15.2.0 and temporarily symlinked the older 14.2 SDK in place of 14.4 and the qmk install completed just fine, albeit slow as ever (for me at least) as it's still compiling the toolchain locally.

That's useful to know, thanks!

It appears the Sonoma ARM64 GHA runner currently does not have the 14.4 SDK: https://github.com/actions/runner-images/blob/main/images/macos/macos-14-arm64-Readme.md#installed-sdks

So this probably wouldn't be an issue for building bottles, at least right now. In the meantime though, the runner could very well be updated while I'm still working on the changes for the AVR toolchain.
