What is the point of porting Aros to Efika?
For x86 version it is a good way to find bugs. It's also a good way to be sure source code is endian agnostic and portable.
It could open the doors to other stuff like integration of 68k emulators like Asgard (written in ppc asm for MacMame) or making AROS more compatible with MorphOS/AmigaOS4
