Jeff Law 0c8679e080 Avoid using common symbols in v850 libgloss
I've had this lying around for probably a year or two at this point.
It just changes all the instance of "errno" from a common symbol to an
extern.  I can't offhand recall where the actual definition is, but it
certainly exists in the generic code.
