OK, this makes much more sense now, thanks! 

I would actually add a note that calling an external assembler fails, and, IIUC ("if we understand correctly" :) ), it's just unavailable on `arm64`. Basically, I think it's worth mentioning the rationale for the claim that's being made:

I am not expecting you to dig into this any further - I'm just asking for some extra clue in the comment for anyone who might want to investigate this :)
