In case it's useful - I hit the error above `error: invalid operand in
inline asm: 'fstcw ${0:w}'` and `error: unrecognized instruction mnemonic` when
compiling Numpy with `clang-cl`, but not with `cl` (MSVC). The invalid
mnemonic is, as you see, `fstcw`, which is x86 specific :
https://tizee.github.io/x86_ref_book_web/instruction/fstcw_fnstcw.html#store-x87-fpu-control-word
. I wonder whether there is some conditional statement to detect ARM64, that
is failing with this build setup, and defaulting to x86?
