Summary:
[libc++] Exclude posix_l/strtonum fallback inclusion for newlib > 2.4
r338122 changed the linkage of some methods which revealed an existing ODR violation, e.g.:
projects/libcxx/include/support/xlocale/__posix_l_fallback.h:83:38: error: 'internal_linkage' attribute does not appear on the first declaration of 'iswcntrl_l'
inline _LIBCPP_INLINE_VISIBILITY int iswcntrl_l(wint_t c, locale_t) {
^
lib/include/wctype.h:55:12: note: previous definition is here
extern int iswcntrl_l (wint_t, locale_t);
These were added to newlib in 2.4 [1] [2], so move them to the already existing include guard.
