Update.
* sysdeps/unix/sysv/linux/sigwait.c (do_sigwait): Make sure SIGSETXID is not blocked. * sysdeps/unix/sysv/linux/sigwaitinfo.c (do_sigwaitinfo): Likewise. * sysdeps/unix/sysv/linux/sigtimedwait.c (do_sigtimedwait): Likewise. * sysdeps/unix/sysv/linux/sigprocmask.c (__sigprocmask): Likewise. * sysdeps/generic/sigfillset.c (sigfillset): Don't set SIGSETXID.
