[PATCH]: (newlib) Allow wcschr(x, L'\0')

[Bob Cassels]

This simple patch for newlib allows using wcschr to find pointers to null 
characters, rather than returning NULL.  I hope it's simple enough to not 
require paperwork.

        * libc/string/wcschr.c: (wcschr): Look for character first, then 
for
        end of string, so you can do wcschr(x, '\0').
