Under what circumstances would a non-x86_64 target build with
--enable-mathvec?

When they have their own API/ABI standard to implement and provide
in libmvec.so?

What's wrong with simply producing a libmvec.so that has no public
symbols?

It simplifies everything to just always ship libmvec.so, even if
it's empty.
