adding Irix (and, to a lesser extent, Solaris) userland emulation to QEMU

Alexander Graf 09716e45a0 sigfd: use pthread_sigmask Qemu uses signalfd to figure out, if a signal occured without the need to actually receive the signal. Instead, it can read from the fd to receive its news. Now, we obviously don't always have signalfd around. Especially not on non-Linux systems. So what we do there is that we create a new thread, block that thread on all signals and simply call sigwait to wait for a signal we're interested in to occur. This all sounds great, but what we're really doing is: sigset_t all; sigfillset(&all); sigprocmask(SIG_BLOCK, &all, NULL); which - on Darwin - blocks all signals on the current _process_, not only on the current thread. To block signals on the thread, we can use pthread_sigmask(). This patch does that, assuming that my above analysis is correct, and thus renders Qemu useable on Darwin again.
