[Bug libc/748] New: SA_RESTART flag in sigaction is broken

["sebastien dot decugis at ext dot bull dot net" <sourceware-bugzilla at sources dot redhat dot com>]

When the SA_RESTART flag is set when installing a signal-catching function with
sigaction(), the signal should not cause an interruptible function to return
with error EINTR but instead the function should restart silently.

The attached test case shows that this behavior is broken on glibc 2.3.4 -- the
sem_wait function, when interrupted, returns with error EINTR.
