Compilation error: forceNonADXArch undefined.

../../go/pkg/mod/github.com/kilic/bls12-381@v0.0.0-20200316214105-3714b4039cbf/arithmetic_decl.go:13:45: undefined: forceNonADXArch

I've imported the package and then vendored it using go mod vendor. No idea why the error didn't appear when running go test on the package directly. Sadly I don't have a minimal test case yet.

This flag is mostly used for testing non adx backend. Now the position of flag is fixed. It builds.
