commit 730bbab2c39dd615c31c924041b4d16d7f107ae0
Author: H.J. Lu <hjl.tools@gmail.com>
Date:   Wed Jan 6 12:37:04 2016 -0800

    Mark internal unistd functions hidden in ld.so

    Since internal unistd functions are only used internally in ld.so and
    libc.so, they can be made hidden.  __close, __getcwd, __getpid,
    __libc_read and __libc_write can't be hidden in ld.so on Hurd since they
    will be preempted by the ones in libc.so after bootstrap.

        [BZ #19122]
        * include/unistd.h [IS_IN (rtld)]: Include <dl-unistd.h>.
        * sysdeps/generic/dl-unistd.h: New file.
        * sysdeps/mach/hurd/dl-unistd.h: Likewise.
