[PATCH] i386: Hide __old_readdir64 [BZ #18822]

Hide internal __old_readdir64 function to allow direct access within and libc.a without using GOT nor PLT.

I will check it in after testing on i686.

            [BZ #18822]
	    * sysdeps/unix/sysv/linux/i386/olddirent.h
	    (__old_readdir64): Add libc_hidden_proto.
	    * sysdeps/unix/sysv/linux/i386/readdir64.c
	    (__old_readdir64): Add libc_hidden_def.
