What would you like exactly to share?

When it makes sense to share the code it can be shared. That is already
done today. But the existing Makefile mechanisms work fine for that.

Making sense: 
- There is actually a lot of shared code
- The supported hardware is the same (remember x86-64 is only for 
modern x86 hardware, while i386 has a much longer legacy) 
- No ifdefs
