Build failure on macOS 15.6.1 #1343
Description
I'm updating vcpkg's build lab to macOS 15.6.1 and ggml:arm64-osx is failing with:

To reproduce, get an arm64 mac, install Xcode, then:
git clone https://github.com/microsoft/vcpkg
./bootstrap-vcpkg.sh
./vcpkg install ggml
I'm sorry I don't have enough understanding of these ARM CPU features in order to correctly debug this and will be forced to disable ggml testing in our lab for now.
