Cannot build or crosscompile for arm64

[Teque5]

I tried crosscompiling with env GOOS=linux GOARCH=arm64 CGO_ENABLED=1 CC=aarch64-linux-gnu-gcc go build and then I tried natively building with go get -x github.com/barnex/fftw and in both scenarios I got

cd /home/teque5/go/src/github.com/barnex/fftw/internal/double

This similar issue concludes that a NEON implementation is required. I understand if this is a wont fix.
