A few architectures have a different call signature for pipe().
Since those architectures are the minority, place the prototype
at the end of the SYNOPSIS, rather than the start.

My initial reading of this was that type modifiers were probably
not supported. But they are, and this is actually documented
further up, in the type modifiers documentation. But to make it
clearer, let's copy the language that printf(3) has in its %n
section.

The CLONE_* constants seem to be available from either
<linux/sched.h> or <sched.h>, and since clone3() already
includes <linux/sched.h> for 'struct clone_args', <sched.h>
is not really needed, AFAICS; however, to avoid confusion,
I also included <sched.h> for clone3() for consistency:
clone() is getting CLONE_* from <sched.h>, and it would confuse
the reader if clone3() got the same CLONE_* constants from a
different header.

AFAICS, there's no reason to include that.
All of the macros that this function uses
are already defined in the other headers.

<sys/time.h> is not needed to get the function declaration nor any
constant used by the function. It was only needed (before
POSIX.1) to get 'struct timeval', but that information would be
more suited for system_data_types(7), and not for this page.

<sys/time.h> is not required by any of the function declarations
