Example won’t compile on x86 MacOS

[maxpoletaev]

I'm not sure if macOS is supported, but I'm getting this error when I try to run an example from the README:

$ ./goat example/src/avx_mul_to.c
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/machine/_types.h:36:1: architecture not supported
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/sys/_types.h:55:25: `__darwin_blkcnt_t`: expected declaration: IDENTIFIER
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/sys/cdefs.h:1022:1: Unsupported architecture
/Library/Developer/CommandLineTools/usr/lib/clang/15.0.0/include/immintrin.h:14:1: "This header is only meant to be used on x86 and x64 architecture"
/Library/Developer/CommandLineTools/usr/lib/clang/15.0.0/include/mmintrin.h:14:1: "This header is only meant to be used on x86 and x64 architecture"
/Library/Developer/CommandLineTools/usr/lib/clang/15.0.0/include/mmintrin.h:1288:27: `__m64`: expected primary-expression
/Library/Developer/CommandLineTools/usr/lib/clang/15.0.0/include/xmmintrin.h:14:1: "This header is only meant to be used on x86 and x64 architecture"

It works just fine if I compile it with Clang. The error seems to be coming from the C parser (modernc) that this tool uses, but I'm not entirely sure what's causing it.
