the wrapping for sigreturn in libc_r was removed, the alpha bits for libc were overlooked and still had a reference to the wrapped version of sigreturn (_thread_sys_sigreturn). libc_r has been totally broken for alpha since then. This change does not apply to -current. Reported by: Bernd Walter

libc_r doesn't provide a wrapper for sigreturn(2).

(This change isn't applicable to -CURRENT which doesn't hide syscalls.)
