libc: fix signal handling in system()
When built without NPTL support (or for a sparc target), the system() function doesn't conform to its specification. Namely, it uses signal() to install/save/restore signal handlers, which may break applications using custom handlers installed with sigaction(). In addition, it resets the SIGCHLD handler to SIG_DFL instead of blocking the signal, which may result in "lost" signals if a custom handler was installed. Fix system() by replacing uses of signal() with appropriate calls to sigaction() and sigprocmask(). Signed-off-by: Richard Braun <rbraun@sceen.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
