    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.  Some functions can't be hidden in
    ld.so on Hurd since they will be preempted by the ones in libc.so after
    bootstrap.

    	* sysdeps/generic/dl-unistd.h: New file.
    	* sysdeps/mach/hurd/dl-unistd.h: Likewise.

    Mark ld.so internal mmap functions hidden in ld.so
    
    Since ld.so internal mmap functions are only used internally in ld.so,
    they can be made hidden.  Don't hide __mmap on Hurd, since __mmap in
    ld.so will be preempted by the one in libc.so after bootstrap.
