>Description:
	The NetBSD kernel cannot be built if you have the COMPAT_LINUX
	switched on, and SYSMSG, SYSVSEM and SYSVSHM all switched off. The
	problem is that the without some IPC, the functions
	linux_to_bsd_ipc_perm and bsd_to_linux_ipc_perm in linux_ipc.c are
	superfluous, and the compiler warns about this. Since -Werror is
	on, this stop compilation.
>How-To-Repeat:
	Enable COMPAT_LINUX and comment out SYSV* in a kernel config file, 
	and try and build it.
>Fix:
	wrap some #if directives around various functions in linux_ipc.c
