Since internal unistd functions are only used internally in ld.so and
libc.so, they can be made hidden.
[BZ #19122]
* include/unistd.h (__libc_check_standard_fds): Add
attribute_hidden.
IS_IN (rtld)] (__access): Likewise.
IS_IN (rtld)] (__brk): Likewise.
IS_IN (rtld)] (__close): Likewise.
IS_IN (rtld)] (__getcwd): Likewise.
IS_IN (rtld)] (__getpid): Likewise.
IS_IN (rtld)] (__libc_read): Likewise.
IS_IN (rtld)] (__libc_write): Likewise.
IS_IN (rtld)] (__lseek): Likewise.
IS_IN (rtld)] (__profil): Likewise.
IS_IN (rtld)] (__read): Likewise.
IS_IN (rtld)] (__sbrk): Likewise.
