Please use:
include/$arch/user-asm/xxxx.h
include/user/xxxx.h

This allows us to

1) To include file foo.h we still distingush between user versus user-asm:
#include <user/foo.h> (include/user/foo.h)
#include <user-asm/foo.h> (include/$arch/user-asm/foo.h)

2) No symlinks needed - just proper options to gcc

This should do it for the top-level makefile:
