[AArch64] Fix out of range branch from ioctl() and clone()
2013-05-12 Marcus Shawcroft <marcus.shawcroft@linaro.org> * sysdeps/unix/sysv/linux/aarch64/clone.S (__clone): Do not call sycall_error directly with a confitional branch. * sysdeps/unix/sysv/linux/aarch64/ioctl.S (__ioctl): Do not call sycall_error directly with a confitional branch.
