I'm sorry but I know very little about the target I have just
inherited the task of making the cross compiler from a colleague.
This is the target I have been instructed to use and also why I have
none of the system headers of libs for it. 

However Following another response to my post I rebuilt newlib and
removed the --without-headers flag and that solved the errors.
