Craft on M1 (arm) macOS

[Albert Vaca Cintora]

Hi,

Is somebody using Craft on an ARM-based macOS already? I tried it
today but libfftw is failing to build:

/Users/albert.cintora/kde/build/libs/libfftw/work/fftw-3.3.8/simd-support/x86-cpuid.h:208:42:
error: invalid output constraint '=a' in asm

It looks like it's trying to build x86 assembly and failing, probably
because something isn't aware of my hardware (even though I have `ABI
= macos-clang-arm64` in CraftSettings.ini).

Is this an unexpected bug or am I entering uncharted territory by
trying to build on ARM?
