Newlib changed ctype.h recently[1] by moving the short labels from ctype.h intro the private namespace in ctype_.h. This broke embedded builds due to them no longer being found. Instead they now expose the long names to match glibc. This patch now uses the short or long names depending on is the short ones are defined or not.
