We don't support this today. I.e, we can only build a pure 64 bits
system, or a pure 32 bits system. But we don't support multiarch, with
one part of the system using 64 bits libraries, and another part of the
system using 32 bits libraries.

The main problem is that it wouldn't be easy to define in menuconfig
which package should be built 32 bits vs. which package should be built
64 bits.

Best regards,

Thomas
