Add new fnmatch code, for now mbstate_t and mbsrtowcs are depending on UCLIBC_HAS_LOCALE, making the new object about 5k, else it would be 10k

+	  been in uClibc for quite a long time but hasn't seen too many
+	  updates.  It also has some known issues when dealing with uncommon
+	  corner cases and multibyte/unicode strings.  However, it is quite
