Mark internal time functions with attribute_hidden [BZ #18822]
Mark internal time functions with attribute_hidden to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * include/time.h (__tzstring): Add attribute_hidden. (__tzfile_read): Likewise. (__tzfile_compute): Likewise. (__tzfile_default): Likewise. (__tzset_parse_tz): Likewise. (__offtime): Likewise. (__asctime_r): Likewise. (__tzset): Likewise. (__tz_convert): Likewise. (__getdate_r): Likewise. (__getclktck): Likewise.
