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.
I've moved the TILE-Gx and TILEPro ports to the main sysdeps hierarchy,
along with the linux-generic ports infrastructure. Beyond the README
update, the move was just
git mv ports/sysdeps/tile sysdeps/tile
git mv ports/sysdeps/unix/sysv/linux/tile \
sysdeps/unix/sysv/linux/tile
git mv ports/sysdeps/unix/sysv/linux/generic \
sysdeps/unix/sysv/linux/generic
I updated the relevant ChangeLogs along the lines of the ARM move
in commit c6bfe5c4d7 and tested the 64-bit tilegx build to confirm that
there were no changes in "objdump -dr" output in the shared objects.
