Linking errors on aarch64 about blst

[dot-asm]

There was an extra commit on top of #26 that should fix this.

On a side note it would be helpful if you don't assume that we can translate "when cross-compiling for aarch64 from x86_64" to sequence of commands:-)

Doesn't really fixes the problem, presumably because build.rs is compiled for host and not for target? Well, I'm still exploring cross-compiling options, some guidance would be appreciated...

Please double-check 83d78c2.

@dot-asm Awesome, that totally fixed it. That was an obvious oversight on my part (trying to use __ADX__ on aarch64).

For reference, the cross-compilation process we use is described here: https://lighthouse-book.sigmaprime.io/cross-compiling.html I figured you wouldn't want to do that (because it requires a tonne of dependencies and takes forever), but in future I'll let you make that choice yourself 😅

Thanks for the merge 😊
