None. But note in your case it is multiarch anyways so maybe you want
--enable-multiarch instead.

Nope, that is not how aarch64 and x86_64 work.

in the case of x86_64 to disable i686 libraries and in the case of aarch64
disable ilp32 libraries (note ilp32 is deprecated but lib64 was used before to
support having arm and aarch64 sysroot as one).
