I think I'm confused. When you say a "64 bit cross toolchain" I read
that as a toolchain for a 64-bit target, and I didn't think the "bit
size" of the host made any difference to Buildroot.
If what you want to do is use Buildroot on architecture A to build a
compiler to run on architecture B for for a target with architecture
C, then that's called a "Canadian Cross", and I don't think buildroot
will do that (unless there's some special case in gcc/binutils for the
IA32 and AMD64 architectures).
You can do it with Crosstool-NG:
