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.
