Compile issues on RPi 32 bit since commit d46bc7b2d176f7efc71eaaedd9aefa8850ab5efa

Hi Amanj,

Since commit d46bc7b2d176f7efc71eaaedd9aefa8850ab5efa I cannot compile Zahak without removing the -mavx from the CFLAGS in fathom.go

Al@RPi4-SSD:~/Engine-Source/zahak-nnue $ make -j5 go clean ./... rm -f engine/nn.go CC=cc CGO_ENABLED="1" go run -gcflags "-B" -ldflags "-X 'main.netPath=default.nn' -X 'main.Version=3253478557873477dc3908536cc02ca9e1a6b447'" netgen/nn.go mkdir -p bin CC=cc CGO_ENABLED="1" go build -gcflags "-B" -o bin ./...

However when I remove this flag, I can compile for 32 bit ONLY, I get these errors on trying the cross-build make

Al@RPi4-SSD:~/Engine-Source/zahak-nnue $ make cross-build -j5 go clean ./... rm -f engine/nn.go mkdir -p bin echo "!!!! WARNING !!!! Cross build will not support Syzygy Probing" !!!! WARNING !!!!
