Avoid using common symbols in v850 libgloss

Jeff Law <[email protected]>
Newsgroups gmane.comp.lib.newlib
Message-ID <[email protected]> 
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.

OK for the trunk?

Thanks,
Jeff
