x86/syscalls/32: Wire up arch_prctl on x86-32
...
Hook up arch_prctl to call do_arch_prctl() on x86-32, and in 32 bit compat
mode on x86-64. This allows to have arch_prctls that are not specific to 64
bits.
On UML, simply stub out this syscall.

um: kill thread->forking
...
we only use that to tell copy_thread() done by syscall from that
done by kernel_thread(). However, it's easier to do simply by
checking PF_KTHREAD in thread flags.
Merge sys_clone() guts for 32bit and 64bit, while we are at it...
