Hide internal __ioctl function [BZ #18822]
Hide internal __ioctl function to allow direct access within libc.so and libc.a without using GOT nor PLT. __GI___ioctl is defined when sysdeps/unix/syscalls.list is used to generate ioctl. Otherwise libc_hidden_def is needed explicitly. [BZ #18822] * include/sys/ioctl.h (__ioctl): Add libc_hidden_proto. * misc/ioctl.c (__ioctl): Add libc_hidden_def. * sysdeps/mach/hurd/ioctl.c (__ioctl): Likewise. * sysdeps/unix/sysv/linux/aarch64/ioctl.S (__ioctl): Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/ioctl.S (__ioctl): Likewise. * sysdeps/unix/sysv/linux/powerpc/ioctl.c (__ioctl): Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/ioctl.S (__ioctl): Likewise.
