Chapter 15 'cross-compiler' has a beginning of a documentation, but it
is nowhere complete (volunteers needed).

Also be aware that some of the cross-compiler targets have been
unmaintained for a while and might not compile anymore.

It is difficult to recommend  an "easy" target, because what is "easy"
in this context depends on your familiarity with the processor

Me, being a retro-computer coder, would choose a 6502, m68k or 8086
board, as I know these processors and architectures.

For you, the R8C might be a target -->

I would do the first steps on a simulator running on a PC (Linux etc,
like qemu-m68k or qemu-misp, or to
learn the first steps, as that is usually easier than to always flash
real hardware and debug there.
