Instructions on setting up the cross compiler for building multiboot.elf

[alexflint]

Describe your bug or error

I am trying to modify the multiboot header in multiboot_header.S. In order to compile my changes, I have a set up gcc and binutils as described over at osdev. But it seems that I need a gcc that supports both 64-bit and 32-bit mode (the magefile uses both -m32 and -m64). How did you configure your cross compiler?
