Indeed, I should have said that the fist link on the osdev wiki covers
that case (which is much simpler than porting GCC to a brand new
architecture).

See https://wiki.osdev.org/GCC_Cross-Compiler for cross compiler
details. That's all you need to be able to use one type of machine to
compile code for a different type of machine.
