This reverts commit 1db4f8f8389f6a935ecd83aff7fcce5d1cf2c0f3.
It is unclear in which way this is breaking sparc systems.
With this change added you get following linking error:
libpthread/nptl/libpthread_so.a(pt-system.oS): In function `__libc_system':

Correct wait4 guard (it is only __USE_BSD)
wait3, system: use __wait4_nocancel

Only really old systems (<=linux-2.0) lack a dedicated vfork system call.
The code that is in place to support them is causing issues with newer
arches that also don't provide a vfork system call -- instead, they do
vfork by calling clone in userspace.
If anyone cares about these really old systems, they can submit a patch
to make the system work with them while not breaking newer systems.

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().

iff we do not have vfork available, which is simpler and more reasonable.

proper threading. Most of this is from Stefan Soucek,
with additions and changes as needed from me.
