Call __setcontext with HIDDEN_JUMPTARGET
i386 __makecontext should call __setcontext with HIDDEN_JUMPTARGET. [BZ #18822] * sysdeps/unix/sysv/linux/i386/makecontext.S (__makecontext): Don't load %ebx when calling __setcontext. Call __setcontext with HIDDEN_JUMPTARGET. * sysdeps/unix/sysv/linux/i386/setcontext.S (__setcontext): Add libc_hidden_def.
