Comment:
As you've noted, cross toolchain for 64 bit platforms on 32 bit platform should work. It's only waiting for someone(TM) to test and enable it. But, I prefer to put them in each template, to allow enabling those packages case by case.
I visited cross toolchain for x86_64 on i686 the other days, for grub-efi, it works there. IMO, let's spell the broken in each template.
