fields which are not defined for the C locale.

field to always contain `no'.

install glibc somewhere other than /.
* shlib-versions: alpha-*-linux-* libc=6.1.
Since sigset_t no longer fits in a register, we can't pass in the
thread's initial mask so easily. Take this opportunity to simplify
the clone implementation by only accepting a single void* argument.

* sysdeps/unix/sysv/linux/alpha/ioctl-types.h: Remove.
Default Linux version should be sufficient.
* sysdeps/unix/sysv/linux/alpha/sigprocmask.c: The osf_sigprocmask
system call wants the sigset dereferenced.
* sysdeps/unix/sysv/linux/alpha/syscalls.list: Add entries for
__syscall_ustat and __syscall_xmknod.
* sysdeps/unix/sysv/linux/alpha/xmknod.c: Include sys/sysmacros.h.
* sysdeps/unix/sysv/linux/sigset.h: Use longs instead of ints.
* sysdeps/unix/sysv/linux/tcsetattr.c: Fix pointer dereferences.
* sysdeps/unix/sysv/linux/alpha/sigsuspend.c: Add comment about
dependency to kernel type.
* sysdeps/unix/sysv/linux/alpha/termbits.h: Correct comment.
