i care the API.

if you really want it be in libc, how about having libc provide a
"locale_t get_static_c_locale();" style API rather than using NULL?
it's better because 1) less code in *_l, 2) autoconf-like can detect
the extension easily, and 3) a portable application can trivially
have a fallback implementation using newlocale+pthread_once.
